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 a handheld FFT Voltage Meter, which measures step and touch voltages according to IN VDE 0101, CENELEC HD637S1, IEEE Std 80-2000 and IEEE Std 81-1983. This allows efficient step and touch voltage measurements in a fast and convenient way.
