An electric fence is a barrier that uses electric shocks to deter animals or people from crossing a boundary. One terminal of the power energizer releases an electrical pulse along a connected bare wire about once per second. Later systems replaced the switch with a solid-state circuit, with an improvement in longevity but no change in pulse width or voltage control. Pulse width is much narrower, often about 10 microseconds. This design works for either battery or mains power sources. This high voltage sensor Fence Hawk RG-7781 takes an electric fence charger pulse and analyzes it for peak voltage, pulse width and period.
The invention provides an electric fence charger of the type that periodically provides high voltage electrical shock pulses through an electric fence wire. And since the fence chargers are typically powered by a low voltage, rechargeable storage battery, it is important that the fence charger operate the charger fence intermittently to provide the narrow pulse width pulses every second or so. A term used to describe electric fence controllers that pulse electricity at regular intervals through a fence, typically at one-second internals. Pulse width refers to the duration of the electrical pulse produced by a capacitive discharge fencer. An easy to build DIY Electric fence to protect a perimeter from wild animals. The frequency and the pulse width can be adjusted using two potentiometers.
Electric fences can have voltages ranging from 3,000 to 10,000 volts. The results for pulse width between 0.025 s and 0.2 s are given in Table 1. Electric fencing is a barrier that uses safe electric shock to deter animals. Pulse width refers to the duration of the electrical pulse produced by a capacitive discharge fencer.
Electric fencing is a physical barrier that uses high pulse electric shocks to deter animals or people from crossing a boundary. Pulse width is much narrower. Those touching the wire and the earth during a pulse complete an electrical circuit and conduct the pulse that causes an electric shock. Later versions replaced switches with solid state circuits, improving longevity but not changing pulse width or voltage control. R is the load resistance in ohms and T is the Total pulse width in seconds. Back to top of page In the calculation that determines the Joule there are variables. This pulse width is what makes electric fence safe. An electric fence is a barrier that uses electric shocks to deter animals or people from crossing a boundary. Later systems replaced the switch with a solid-state circuit, with an improvement in longevity but no change in pulse width or voltage control. Gom, pulse width can be set by adjusting the 22k resistor value appropriately.
