RE: blow out fuses of capasitor bank

About the only thing that causes fuses to blow is too much current.  Not enough information to figure out why you might be seeing too much current.  What kind of damage are you seeing on your capacitors?

RE: blow out fuses of capasitor bank

What fuse rating are you using?

Are these switched or fixed capacitor banks?

RE: blow out fuses of capasitor bank

Are the capacitors individually fused? Are you blowing the main fuses? Is it the same one all of the time? Is the capacitor bank enclosed, outdoors? We have had birds, raccoons and cats step across our old 410kvar 23kv cap bank in our outdoor substaion. You should see what that does to a small animal--not pretty. We have since replaced the old bank with a fully enclosed one. What about lightning strikes, transients? What kind of load are you feeding? We have a fixed bank feeding an electric arc furnace. These can at times single phase as well as other things that can demand above full load current for brief periods.
