Hello fellow listers,

Through my scrounging endeavers I have come across a 25KVA 208 3phase UPS
for free!  It was hit by lightning and was scrapped.  My questions are;

 1) Does anyone have the mathematical formulas for construction of EMI/RFI
filters? This unit has many parts that  can be salvaged such high current
inductors and many AC capacitors.

2)Or does anyone on the list have any 50amp or greater EMI/RFI filters for
