Generator Metering Panel

Along side please find a generator metering panel which illustrates the general metering arrangement required for generator stations. In the LT station the general metering is done directly from generator through isolator. Transformers on the voltage sector and through CT’s on the current sector and using both on power sector.

However the metering is generally fed from the LAVT panels where HT voltage is meterised through HT PT’s. Some of the field PT supply come through PT & CT junction boxes where substation & Ht generator station are involved.

The panel shown above is 3.3 KV Generator metering Panel.
