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
EDS3090:
Can be used in IT systems in which a locating current injector PGH471 or an IRDH575 is already
installed.
EDS3090PG:
Can be used in IT systems in which neither a locating current injector PGH471 nor an IRDH575 is
already installed.
Supply voltage for the locating current generator PGH185 supplied:
AC 50…60 Hz, 230 V
EDS3090PG-13:
Can be used in IT systems in which neither a locating current injector PGH471 nor an IRDH575 is
already installed.
Supply voltage for the locating current generator PGH185-13 supplied:
AC 50…60 Hz, 90…132 V
2. Permissible system voltage in the main circuits:
– Insulation fault location in IT systems up to AC 42…460 Hz, 0…575 V and DC 0…504 V
– Insulation fault location using AGE185 up to AC 42…460, Hz 500…790 V and DC 400…960 V
EDS3096PG:
Can be used in IT systems in which neither a locating current injector PGH471 nor an IRDH575 is
already installed.
Supply voltage for the locating current generator PGH186 supplied:
AC 50…60 Hz, 230 V
Insulation fault location, also in IT systems electrically isolated on all poles
