69 kV to 345 kV air break switch resistances

69 kV to 345 kV air break switch resistances

(OP)
Does anyone know of a source or standard that provides what acceptable resistance values can be on group operated air break switches for 69 kV through 345 kV?  Thanks!

RE: 69 kV to 345 kV air break switch resistances

Try IEC 60694f subclause 6.4.  Referenced in IEEE C37.48

Or IEEE C37.30 and 37.37

RE: 69 kV to 345 kV air break switch resistances

Insulation resistance or contact resistance? For IR try NETA ATS www.netaworld.org for contact resistance let me know what the current rating is and I can give you an idea.
