Ground conductor current
- The effective inner resistance of the ground conductor current measuring device may
be a maximum of 5 . (With higher resistances, measures must be taken to prevent
the occurrence of hazardous contact voltages.)
- The measuring range must comprise at least the values from 0.25 mA to 19 mA.
- The inspection facility must assess the measured current to be an effective value re-
gardless of the waveform.
Contact Current
- The effective inner resistance of the contact current measurement instrument must be
1 k to 2 k.
- If the current test circuit is accidentally connected to a voltage up to 120% of the nom-
inal grid voltage, the user must not be endangered and the test circuit must not be
damaged.
- The inspection facility must assess the measured current to be an effective value re-
gardless of the waveform.
