3.1.2 Insulation fault location equipment type list
It is possible to undertake a residual current measurement in TT and TN systems (earthed systems)
using all the device variants listed below.
The following overview describes which measuring tasks can be undertaken with which models:
Equipment for insulation fault location in main circuits
1. Permissible system voltage in the main circuits:
– Insulation fault location in IT systems up to AC 42…460 Hz, 20…575 V and DC 20…504 V
– Insulation fault location using AGE185 up to AC 42…460 Hz, 500…790 V and DC 400…960 V
