Re: Chokes



to: Sam

Off each HV bushing (if NST) used a 500 Ohm, 100 watt resistor (Digi-Key
Electronics).  After the resistor then thru a 5 turn 14 AWG wound around a
toroid ferrite or straight ferrite.  On the low voltage side, Varisters (20
amp), and a hash choke consisting of 20 turns of # 12 AWG wound on a
ferrite choke in series with both hot and neutral leads.  Use 2 line
filters as I have previously described in series with each other.
