Nettet29. apr. 2012 · The Insulated Power Cable Engineers Association (IPCEA) provides the formula to determine minimum insulation … NettetInsulation resistance is measured between phase conductors and between phase conductors and ground conductors. Good insulation should have very high resistance. An insulation tester applies a high dc voltage to de-energized, isolated components. The instrument then measures the resistance between the two points.
