and capacitive reactance each conductor ground; thus, low (but acceptable) insulation resistance one con-
ductor can effect ground and raise the other two full conductor-to-conductor voltage ground.5 14.5 2.wago.7

Conductor-to-ground insulation level for non-grounded impedance-grounded systems equals that for conduc-
tor-to-conductor, the operating voltage ground any conductor can, practice, approach full conduc-
tor-to-conductor voltage.
