5.1 Maximum transmission distance test
It should be carried out on the actual fence. The length of a single fence line (including the grounding line if there is one) is required to be no less than 95% of the nominal value of the maximum transmission distance of the electric fence pulser, and the power supply voltage is the rated value. The output voltage peak is measured at the beginning and end of the fence line. When the voltage Um at the beginning and end is no less than 2000V, it can be considered that the maximum output distance of the electric fence pulser is no less than the nominal value. The test circuit is shown in Figure 1. Use an electronic oscilloscope to record the voltage waveform on the voltage divider resistor B, measure its peak value U, and use formula (1) to calculate the voltage peak value Ui of the fence line.
