Step and touch voltage tests
At critical locations, such as the fence around your substation, hazardous step and touch voltages can occur. It is, therefore, crucial to measure step and touch voltage at locations in and around the substation in order to ensure safety for persons and animals.
The single-phase fault is simulated in the same way as when measuring ground impedance by injecting a current with a frequency variable current source and by grounding the remote end of your line.
Our test system comes with the HGT1, which measures step and touch voltages according to EN50522, IEEE81 and IEEE 80/81. This allows efficient step and touch voltage measurements in a fast and convenient way.
