Hello All
I have 4 115/24 kV 60 MVA transformer banks with 8% impedance. When all the banks are tied the fault levels becomes high. feeder reactors are used to limit fault current on the feeder side. But 24 Kv side has fault levels that require use of 40 KA breakers. But I am planning to...
Hello All,
I have a 115/24 Kv station with two Banks 60 MVA each and there are feeders going out of the station. Each feeder has a feeder reactor precceding a 25 kAmps breaker. The 3 phase fault level at the Bus with 2 banks tied on 24Kv side is 15KAmps. This is less than the 25 kA breakers...
Hi
I have installed three phase regulators after a transformer.Do I need some sort of station service to operate the regulators. In the drawings, I have show a 50 KVA padmount. I understand that a recloser would require a 50 KVA padmount to operate the D.C controls to open and close the...
