A low‐cost Raspberry Pi based time domain reflectometer for fault detection in electric fences

IET Science, Measurement & Technology
Electric fences used to create protected areas (PAs) are prone to faults that affect their operation. The conventional method of measuring the voltage of the fence periodically to detect faults and walking along the fence to locate the faults is ...
