Posted By Topic: Incoming supply filters?

Mar 09 2020 23:52

Does anyone know what these LC filters are supposed to do?

They are on the incoming supply to an engineering factory. About a 200A~300A supply at a guess.

They are inside a panel with just thumbscrews holding the door closed :(

Harmonic filters?

I've seen similar - but larger - on a PFC unit
