69 kV to 345 kV air break switch resistances 2

[stnbrg1]

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!

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

Or IEEE C37.30 and 37.37

Insulation resistance or contact resistance? For IR try NETA ATS

for contact resistance let me know what the current rating is and I can give you an idea.
