Vlf testers are smaller and more practical than ac testers but output the same amount of power as a 50 hz mains device. Vlf testing of cables is supported in iec 60502 up to 35 kv and in ieee 400 2 up to 69 kv. Acceptable procedures for conducting hi pot testing although varying slightly in technique have been standardized as either a withstand test or a time leaking current test ieee std 400 provides additional information on dc testing and evaluation of the insulation of shielded power cable systems.
