Insulation resistancetestingIntroductionInsulation resistance testers canbe used to determine the integ-rity of windings or cables inmotors, transformers, switch-gear, and electrical test method is determinedby the type of equipment beingtested and the reason for test-ing. For instance, when testingelectrical cabling or switchgear(low-capacitance equipment)the time-dependent capacitiveleakage and absorption leakagecurrents become insignificantand decrease to zero almostinstantly. A steady conductiveleakage current flow is reachedalmost instantly (a minute orless) providing perfect condi-tions for the spot-reading/short-time resistance test.
