Despite the fact that AC chargers are hooked into an electrical outlet, don’t expect a hefty power bill. AC chargers are typically passive devices that only require a little amount of energy on a daily basis. Most users will notice a negligible change in their energy consumption, which will equal to less than a dollar over the course of a month.
- Killowatt Hours Utilized per Month = (The charger’s watts per day x days used per month)/1,000
Then you simply multiply that number by the result above to find out how much your electric company charges you per kilowatt hour.
- The average Zareba fence charger consumes approximately 33 watts per day. So 33 watts times 31 days is 1,023. That equals 1.023 kilowatt hours per month when multiplied by 1,000.
The average cost of a kilowatt hour in the United States is 12 cents. The cost of running that electric charger for the entire month is 3 cents if we multiplied 1.023 by 12 cents (.12).
How Does an Electric Fence Work?
The principles are the same whether you’re using a Netting System or a regular Stock Fence.
An electric fence is made up of two arms that are connected by an open electrical circuit.
The first arm is the fence, which is connected to the Fence Energiser’s power connector. Plastic insulators or an air gap of at least 3cm must completely isolate this portion from any other conductive material (earth, leaves, grass, trees, metal, or brick). It doesn’t have to loop back on itself, and it can be as short as one line from the energiser.
2/. The second arm is the ground, which is connected to the energiser’s Earth terminal through the earth stake/post.
As a result, an OPEN electrical circuit (as depicted in the diagram) remains open, waiting for an errant animal to close it.
When the animal (as illustrated in the diagram) contacts both the live fence and the ground at the same moment, the electrical circuit is closed. This allows electricity (electrons) to flow from the fence to the ground, through the target animal, and back to the energiser via the earth stake, causing the animal to receive an electrical shock when it comes into contact with the wire.
What is the effect of Electric Current on an Animal?
When an animal comes into contact with an electrical wire, it experiences a muscle contraction comparable to a muscle cramp in humans. With a constant supply of current, such as that provided by mains electricity, the gripping effect occurs, which is extremely dangerous because the victim is unable to release the source of the current. The cramping caused by an electric fence is only temporary, and the person can move away from the source of energy. This unpleasant sensation will be associated with touching the fence, and the animal will be discouraged from doing so in the future. As a result, the fence does not cause physical harm to the animal, but rather serves as a teaching tool to keep it from happening again.
Is an Electric Fence Dangerous?
An electric fence is not inherently unsafe. Although the voltage passed through the cables is large, the current or amplification (amps) is quite low. As long as the current or amps are the same, a 220-volt shock will hurt just as much as a 10,000-volt shock. Amps are the ones who murder you. Electric fence energisers generate a lot of voltage (about 8,000 volts) but very little amperage or current (around 120 milliamps). This is a 120-thousandth-of-an-amp signal. It shouldn’t even be capable of killing a squirrel.
This output is rendered safe in two methods. First, the flow of electrons from the capacitor is released in regular pulses of high voltage but low current. The amperage component of the electrical charge is lowered to values between 15 and 500 milliAmps. (The majority of units run between 100 and 150 milliAmps)*. Electricity from the mains is between 13 and 15 amps.
Second, electrical energy is transmitted through the cables in pulses. This implies it sends a pulse of electricity down the line once every second for 1/300th of a second. The pulsating current is caused by the fact that if the wires are touched and a shock is delivered, whatever touches them has a chance to extricate itself. If the current did not pulse (as it does in most electrical appliances such as a hair dryer, radio, or toaster), whatever came into contact with it would continue to be shocked, and the muscles would react to the “grabbing effect” of an electrical impulse until the power was turned off or something pried them off.
When you touch a door, you get roughly 30000 volts at 5 milliamps for 1/1000th of a second, which is uncomfortable but not enduring.
2/.Primary Electricity 220 volts at 13 amps, which is steady, unpleasant, and causes death on a regular basis.
Electrical fencing is a safe product since it uses low amps and a pulsing current. Electricity is dangerous because of the amperage within the electrical charge and the continual connection.
This link will provide you with a more detailed explanation of the safety of an electric fence.
What Happens if a Child Touches it?
A youngster will be shocked if they touch both the hot and ground wires. It will hurt for about 10 minutes, but it will not be incapacitating, leave a burn mark, or cause death. Electric fencing cannot kill or permanently harm anyone because of its low current and pulsating nature. It is, nevertheless, strongly urged that youngsters be kept away from an Electric Fence. All of the energisers on sale are compliant with EU laws and have been certified for use in the intended applications.
What if a Dog Touches it?
The same as a child or anything else that comes into contact with it. They’re going to be OK. For a short time, it will hurt, but they will learn not to touch it again. One difficulty that could arise is if an animal becomes stuck in the fence for an extended period of time and is unable to free itself. This could be due to horned creatures, hedgehogs that curl up into balls, or any other reason they’ve become imprisoned. This differs for different animals and, sadly, might lead to the animal’s death. Fortunately, this is extremely rare; in my 30 years of dealing with electric fencing, I’ve only heard of three instances where an animal was killed. As a result, HoriSmart energisers were created, which are capable of detecting what is touching the fence and treating it appropriately, thus boosting the level of safety.
How Much Energy does an Energiser use?
There isn’t much. The energisers are normally plugged into a 220 volt outlet and consume very little power. The energiser takes a low voltage and converts it to a high voltage that is applied to the wires. The unit consumes extremely little energy because it pulses for such a brief time every second and the fence is not a complete circuit. A 1 joule unit typically consumes 4 watts, which is comparable to a 40 watt light bulb. As a challenge is formed on the fence, energy consumption will rise; the more plant that grows on it, the more electricity it will use.
May I Install an Electric Fence Myself?
Electric fencing is simple and straightforward to install. It lends itself to do-it-yourself, and the majority of users install it themselves. If you’re thinking of doing something like this, it’s a good idea to do some research first. When using electric fencing to achieve your aim, there are a few things to keep in mind. Installing the wire spacing properly, for example, such that a target will strike both the hot and ground wires, causing a shock, and ensuring that the live (or hot) wire contacts NOTHING BUT PLASTIC. Keep in mind that the most common cause of an electric fence’s failure is poor grounding.
An electric fence generates how many amps?
A little farm stood across the street from my elementary school, surrounded by an electric fence. Many of us youngsters would dare one other to touch the barrier during recess. Of course, the movie Jurassic Park was my sole exposure to electric fences at the time. If you’ve seen the movie, you’ll understand why I was frightened of touching an electric fence. I eventually worked up the bravery to touch the fence, only to be greeted by a faint pulsing tingling. So, given that we live in a vast rural community with a lot of electric fences, the issue arises: Are electric fences dangerous?!
Because touching an electric fence leaves a vivid and painful recollection, and because the voltages are high compared to conventional mains electricity, most people will conclude that the risk to life and limb is also great. Contrary to popular belief, this is not the case. Consider that hundreds of thousands of individuals are “exposed” to millions of electric fences every day throughout the worldyet electric fences are responsible for (but not usually) less than one serious accident each year. Consider the number of people injured or killed each year by tractors, skid loaders, ladders, PTO shafts, balers, mowers, combines, bulls, stallions, shotguns, knives, and other farm equipment. This isn’t to say that there aren’t some dangers. There is, in fact, a minor amount of danger. With risk comes the risk of liability for the fence’s owner.
Although the voltage passed through the cables is large, the current or amplification (amps) is quite low. As long as the current or amps are the same, a 220 volt or 110 volt shock will hurt just as much as a 10,000 volt shock. To power machines and utensils, these currents are steady and have high amperages (13 and 20 Amps). Muscles, whether human and animal, stiffen up when exposed to 220 or 120 volts and are well grounded in dew or a good ground. In that instance, there is no way to get free from the fence. You’re just literally clamped to the wire, and no matter how hard you try, you can’t let go the constant voltage keeps your muscle frozen, and the enormous current will fry you.
The high voltage (about 8,000 volts) produced by electric fence energizers creates a very visible spark that attracts the target’s attention. They do, however, reduce the lethal amps to a low amperage of roughly 120 milliamps (It varies with manufacturers). This is 120 kilowatts of power ( normal mains electricity is 13 Amps). It shouldn’t even be capable of killing a squirrel.
This output is safe in two ways. First, the flow of electrons from the capacitor is released in regular pulses of roughly 1/300th of a second, spaced about a second apart. The amperage component of the electrical charge is lowered to values between 15 and 500 milliamps. (The majority of units run between 100 and 150 milliamps)* Compare this to the following two instances.
- When you touch a door, you get roughly 30000 volts at.5 milliamps for 1/1000th of a second, which is uncomfortable but not long-lasting.
- Electricity from the mains. Many incidents of people running out lines directly plugged into 220v or 110v circuits, killing both animals and people, have been reported.
Low impedance circuitry, in which a capacitor is charged by a solid-state circuit, is used in modern fence energizers. A thyristor releases the charge when an animal (or a person) comes into touch with the fence. This is an electronic component that functions as an automated switch, allowing for more precise voltage delivery and a considerably shorter shock pulse – typically a few milliseconds. The energy is transmitted through the wires or conductors in pulses. This implies it sends a pulse of electricity down the line once every second for 1/300th of a second.
The rationale for the pulsating current is that when the wires are touched and deliver a shock, whatever touches it has an opportunity to get away since touching an electrical wire generates a muscle contraction in the animal that is akin to a muscle cramp in humans. With a constant supply of current, such as that provided by mains electricity, the gripping effect occurs, and the victim is unable to release the source of the current. The cramping caused by an electric fence is only temporary, and the person can move away from the source of energy. This unpleasant sensation will be associated with touching the fence, and the animal will be discouraged from doing so in the future.
If the current did not pulse (as it did in most electrical appliances such as hair dryers, radios, and toasters), anything that contacted it would be shocked until the power went off or they were pried off.
One difficulty that could arise is if an animal becomes stuck in the fence for an extended period of time and is unable to free itself. This could be due to horned creatures, hedgehogs that curl up into balls, or any other reason they’ve become imprisoned. This differs for different animals and, sadly, might lead to the animal’s death. Fortunately, this is extremely rare; in my 30 years of dealing with electric fencing, I’ve only heard of three instances where an animal was killed. As a result, the horismart energisers were created.
Fencer/Energizer
All equipment should be obtained from a reputed company, as this ensures high-quality materials backed by your provider. When choosing an energizer, remember that bigger is preferable. To put it another way, buy a fencer that is a little bigger than you need. This will ensure that enough voltage is going through the wire to handle brush and wet grass sucking up some of the power, as well as future additions. Owing to thicker hair coats on the livestock and the lack of a proper footing due to snow, a fundamental rule of thumb is that you need no less than 2000 volts in the summer and 4000 volts in the winter.
- Install a fence where rodents won’t be able to nibble through the wires (preferably in a building)
Ground Rods
The most crucial component of the fence is the grounding system. Make sure your ground rods are properly installed. You’ll need a minimum of three 6-8 foot long rods, spaced at least 2 meters apart and 3 meters apart from the energizer. Galvanized wire is used to link the rods and clamps to the energizer.
Check to determine sure the fence is correctly grounded once it has been installed. This is done by grounding out the fence with a metal bar and then using a volt meter to check the ground rods. If your volt meter reads greater than 200 volts, you’ll need more ground rods. With a properly grounded fence, there should be no volt reading on the meter.
Wire
- The first wire should be 22 inches from the ground, and the highest wire should be 40 inches.
- At least every 1/2 mile, the top and bottom wires should be connected.
Insulators
- Purchase high-quality insulators that require two nails at the top and bottom. Insulators that just require one nail will take power from the fence.
- Insulators are covered by a multi-year warranty from a variety of manufacturers, and broken ones are replaced at no cost to you.
Braces
- Make sure the horizontal brace is 2.5 times the vertical brace post’s height.
- There are a variety of ways to construct braces, but the most important is to have corner posts (4 to 5″) that are at least 3.5 feet in the ground. The horizontal brace and straining wire must also be properly fitted.
How long does an electric fence’s battery last?
We usually advocate using leisure and deep cycle batteries with electric fencing because they are designed to be depleted and recharged often, unlike automobile batteries. If properly cared for, this battery should last for 200 cycles and up to 2-7 years.
Are electric fences AC or DC powered?
An energizer is required to generate the charge required to power an electric fence (also known as a fencer or charger). There are energizers that use either AC (plugs into an outlet) or DC (battery, solar panel, or both) electrical current. The majority of farm-fence energizers utilise the power to send a short pulse of very high voltage and low current to the fence. Every two seconds, the majority of these so-called short-shock chargers unleash a tremendous burst of electricity in a concentrated voltage for a fraction of a second. To let you know it’s working, many produce a continuous “tick tick tick” along with the pulse. This burst swiftly dissuades the interested animal from exploring its escape route further, ensuring that they do not suffer too much of a shock.
Energizers are classified according to how many acres or miles of fence they can power. For example, a typical fencer may charge between $80 and $90 for 20 to 30 acres of land. Smaller energizers that can charge up to 8 or 10 acres are available, giving you the freedom to pick a solution that matches your individual demands. It’s important to remember that the number of acres or miles the charger can power is for a single line, and many animals require a multiline fence. When it comes to researching fencers, I find the mileage rating to be significantly more useful.
Sending a pulse down the fence wire is only part of the tale because electricity travels in circles. The electrical circuit is open with a correctly functioning electric fence and nothing connecting the hot wire to ground… it’s like a switch that’s been turned off. The electrical pulse then diminishes after traveling the length of the fence. When an animal (or a sloppy rancher) touches the hot wire, the pulse passes through them and into the ground, where it is carried back to the energizer’s ground pole through ground rods driven into the ground. The unwary beast’s guttural explosion indicates that the switch has been flipped on… the electrical circuit is complete, but only for a fraction of a second.
Is it possible to touch an electric fence without getting shocked?
Inside your home, there are two types of electrical outlets: high-amperage and low-voltage (which is dangerous). If someone comes into contact with an electrified fence by accident, they will be shocked. Always take caution while approaching an electric fence and avoid contacting it with your head or upper torso.
How many amps does it take to kill someone?
While any current greater than 10 milliamperes (0.01 amp) can cause uncomfortable to severe shock, currents of 100 to 200 milliamperes (0.1 to 0.2 amp) are deadly.
How unpleasant is it to be encircled by an electric fence?
We are all surrounded by electricity, which provides light, warmth, hot food, telephones, hair dryers, and even maintains farm animals in their proper places. It’s also supplying energy to the gadget on which I’m typing this and which you’re reading! When there is a power outage, we all know how devastating it can be for us.
Electrical power, like most inventions, can, nevertheless, be deadly. Electrical shocks are fairly common, typically unintentional, and largely avoidable. We should all be aware of the risks and understand what to do should one occur.
- The flow of electricity through the body can cause cells to malfunction. Heart cells are an example of cells that, in severe situations, might cause the heart to stop beating.
- In the body, electrical energy is transformed to heat energy. This can result in skin burns at two locations: where the electricity entered the body and where it departs the body. Deeper and more serious burns to the tissues and organs ‘hidden’ inside the body, for example, causing damage to the nerves, muscles, and organs, are commonly the result of superficial burns on the skin. When electricity ignites objects near the person, such as clothing, bedding, dry grass/bushes, plastics, and so on, flame burns can result.
- During or after the electrical shock, people may fall, be thrown, or experience powerful muscle contractions, resulting in physical damage. Cuts, bruises, broken bones, brain injuries, and dislocated joints are just a few examples.
- Shock waves of up to 20 atmospheres (equivalent to a bomb) can be generated by lightning and subsequently passed into the body. Eardrums, blood vessels, and other internal organs may be damaged as a result of this.
For almost a century, electric fences have been deployed all over the world, initially for security and border control during conflicts. In the 1930s, the technology was developed for use in agriculture to keep farmed animals contained inside their fields and cages while keeping wild animals out (and people). Commercial, military, government, and aeronautical structures and grounds are still protected by electric fencing.
All electric fences should have conspicuous signage advising of their existence at regular intervals throughout their length.
An electric fence is made up of posts (made of wood or insulated metal) that are connected by powerful wires. A power energizer is a component that converts ordinary electricity (for example, 220V AC in Switzerland) into an intermittent pulse of high voltage electricity. This pulse then runs once every second along the whole length of the wire. When the pulse happens, you (or an animal) may hear a gentle buzz or click. The energy runs down into the ground via a metal rod inserted into the ground if nothing else touches the electric fence.
Each pulse’s electrical energy shall not exceed 5 joules at 50 ohms of resistance, according to EU law from 2010. This is the equivalent of a dim domestic light bulb in terms of output power.
If they are also in contact with the earth, such as with their feet or hooves on the ground, the electricity will preferentially pass through their bodies rather than via the metal rod. A fast electrical shock will be felt by the human or animal, which might range from a slight buzz to a very painful jolt. The power is normally DC and is discharged in less than a second (direct current). The severity of the shock is determined by several factors:
The electrical shock will run through both people if there is a chain of two or more people in contact with the fence, such as a toddler clutching the hand of an adult who then touches the fence.
To an escaping animal or trespassing person, an electric fence shock should be nothing more than an unpleasant deterrent. However, we can never be certain of the equipment’s and fence’s reliability, or the technical standards followed in other nations.
In fact, you may not be aware of the particular scientific characteristics of an electrical shock that has just occurred, but keep in mind that all electric shocks can cause injuries and, in the worst-case scenario, death, and must thus be handled seriously.
The following is a First Aid Protocol for examining and treating an electrically injured individual while remaining safe.
1. DISCONNECT THE POWER OR BREAK THE ELECTRICAL CIRCUIT
Remember that rushing in to assist someone who is still in contact with a running electrical current may cause you to be shocked as well. Consider this: your personal safety comes first!
Switch off the electricity at the mains supply in a domestic scenario (e.g., at home or at school). A large switch is normally located near the fuse box or in a similar location. Do you know where the mains switch is located at your home, school, or workplace?
If you are unable to switch off the electricity, you must securely break the circuit of electricity flow:
To begin, stand on something non-metal, such as a couple of phone directories or thick books, or a wooden box.
Then, using a high resistance object such as a wooden chair, a wooden broom, or a thick rope, push or pull the individual away from the electrical source.
The subject is usually no longer in contact with the DC current after receiving an electric fence shock they have either released go due to discomfort or have been thrown clear. However, consider what materials you have in the countryside or in your backpack that you could use to safely break the circuit if necessary.
Stay at least 18 meters (20 yards) away from the shocked individual in a high-voltage situation (e.g. overhead power lines, live train rails). Because such high voltage electricity might jump or ‘arc’ to you if you get too close, this is the case.
Call 144/112 and wait for an authority to turn off the power and isolate you. The injured person should only be approached by emergency personnel.
2. INSPECT FOR A RESPONSE AND TO SEE IF THEY ARE BREATHING PROPERLY (once it is safe to approach the person)
- Regardless of any other injuries, including burns, begin cardio-pulmonary resuscitation (CPR) right away.
- Keep your cool. Water can be used to soothe the burn. Remove all clothing from the area of the burn. Apply a sterile, non-fluffy dressing on the wound. With your speech, eye contact, and soft touch, reassure the person. Wait for the ambulance to arrive to take them to the Clinic.
- Use the ‘6 C’s’ to look for and treat any burns. There could be an entry and exit burn on the skin, but keep in mind that they’re more than likely to have greater ‘hidden’ burns inside their body that require immediate medical attention.
If the shock appears to be minor, they don’t appear to have any skin burns, and you’re not sure if a trip to the hospital is necessary, at the very least call the emergency services on 144/112 to obtain some particular guidance on the case – the person’s age, type of shock, general symptoms, and so on.
- The heart – particularly for those who have had previous cardiac difficulties or who are experiencing chest pain or difficulty breathing. An ECG will be used to monitor the heart’s rhythm (electrocardiogram).
- The skin for blistering or burns, particularly in the folds of the skin, around the joints, and around the mouth.
- The nervous system should be examined for any evidence of a brain injury or damage to the sensory or motor nerves.
- The retina in the rear of the eye and the ear drums are examined for any signs of injury.
- Examining the musculoskeletal system for bruises, swelling, or fractures.
- The urine and blood are tested to see if there is any renal damage or if there are any abnormal electrolyte (salt) concentrations.
The checks may only be performed once, after which the person will be allowed to return home. Alternatively, they may be necessary to stay in the hospital for several hours, if not days, in order to ensure that the body has fully healed.
People have known about the presence and dangers of electricity since the ancient Egyptians. Electric fish on the Nile gave people electric shocks in 2750 BC, according to writings.
To bring it up to date, without the amps and volts to power it, CERN’s Large Hadron Collider would just be a dull empty circular tube. Yes, electricity is dangerous, but perhaps this article will help you understand not just the hazards, but also what to do in the event of an electrical shock and how to be safe.
