Q

A procedure that is not used to de-energize a capacitor bank is

A

Close the oil or vacuum switch

21
Q

Capacitor testing is usually used to find a existing problem rather than preventing a future problem

You can test the insulation’s conduction to see if you have a problem

A

True

26
Q

The field test used to test insulation is called insulation resistance test

A

True

A

True

28
Q

_____________ is the insulation’s ability to prevent current flow

A
