Feeder Reactor
Feeder Reactor
(OP)
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 rating on the feeders.
My question is
If I remove feeder reactors and rather put reactors on the Bus, that would also protect the feeders as there is a breaker with 25 kAmps rating.
Thanks
Timmy

RE: Feeder Reactor
Also, I'm not clear by what you mean by "put reactors on the bus".

How big the inductance of the in-line reactor? You may blow up the bus!

I am trying to figure out how to calculate feeder reactance value to limit fault currents

Please provide some input, how can we still parallel and still limit our breaker ratings.

Various combination for reactors can be applied such as feeders, coupler, etc...
I have read an article before by trench (manufacturer) about this issue and it contains a lot of examples.http://eepublishers.co.za/images/upload/Energize_O...
