3.2.20.1
Description
The following terminals are on the input module IO240 for the low-power instrument transformer (LPIT):
•
4 current inputs for the low-power current transformers in the gas insulated switchgears (GIS LPCT), for
example, rogowski coils
•
4 voltage inputs for the low-power voltage transformers in the gas insulated switchgear (GIS LPVT), for
example, capacitive voltage sensors
•
4 temperature measuring channels (4-wire PT100 thermistor)
The connections are distributed over four 14-pole terminal blocks.
