Frequently Asked Questions about 750-P5-G5-S5-LO-A20-R-E
Should the zero sequence current transformer by a twisted pair of cabling for the GE Feeder Management Relay 750-P5-G5-S5-LO-A20-R-E?
Yes, the cable for the zero sequence current transformer needs to be a twisted pair of cabling. The many current transformer connections and placement has to be exact for the zero sequence current transformer for the ground fault to actually be detected.
How many channels does the GE Feeder Management Relay 750-P5-G5-S5-LO-A20-R-E have for the alternating current inputs?
There are 4 channels for the GE Feeder Management Relay 750-P5-G5-S5-LO-A20-R-E for the alternating currents voltage inputs, with each of them being an isolating transformer. Theres a maximum of 5000:1 ratio that can be used for the voltage transformers.
What are the 3 phase inputs designated to for the GE Feeder Management Relay 750-P5-G5-S5-LO-A20-R-E?
The three phase inputs are only designated as bus voltage and the bus voltage transformer connections are used commonly with wye and open delta. The voltage channels are connected internally as wye and the jumper between phase B terminal and the vcom terminal has to be installed with the delta connection.
