Current Limiting Reactor
Current Limiting Reactor
(OP)
Hi there,
What are the standard formulaes used in desiging an outdoor 44kV current limiting reactor in a substation. Downstream of the reactor is a solidly grounded 44/26kV, 10MVA distribution transformer. Happy if someone could refer me to a section of a book, IEEE or CSA standard?
The purpose of the reactor is to reduce the fault level in the substation.
Thanks.

RE: Current Limiting Reactor
If you have a transformer directly downstream, it might be more cost effective to just build more impedance into the transformer. This won't help you on the 44 kV side obviously.
CLRs are a really good thing to avoid if you can. Just one more thing to fail and generate losses.
