RE: [TCML] Terry Filter MOV heat

["Lau, Gary" <Gary.Lau@xxxxxx>]

The correct number of MOV's to use is governed by the NST voltage.  For a 15kV NST, 8 per side are needed.  With what voltage are you using 7?  Who is using 5?

Per Terry's original documentation:
NST     MOV's per side
9kV     6
12kV    7
15kV    8
