We spared no effort during the development and got some electrical shocks to measure numerous electrical fences manually. To do this, we recorded the characteristics of an energy pulse with the help of a high-quality high-voltage probe and a high-quality oscilloscope.

Do not try to measure an electric fence if you don't exactly know what you're doing. You can seriously damage your valuable equipment.

High-Voltage Probe and Oscilloscope

We went outside and measured the voltage waveform of numerous electrical fences. As we didn't want to fry our expensive oscilloscope, we organized a high-voltage probe for it instead of building one by ourselves. Additionally, we get the confidence that the measured results should at least be somewhat correct. This is important because many steps in the component selection and planning are based on the assumptions we took from these measured results.

Results

The results show us the general shape of an energy impulse on a fence. We observe a shape that is similar to a half sinus wave. The peak voltage varies between 3 kV and around 14 kV. Additionally, we find that the rise time is in the order of 10 μs to 20 μs.

Probing an electric fence energizer right at the start.
Our mobile setup to take fence voltage measurements using a car battery and 230V inverter.
We probed the fence at several different locations and heights.
We also got access to a high bandwidth HV probe.
