6.2　Insulation Resistance Tester

Insulation diagnosis is an important measure to detect insulation defects or faults of electrical equipment.Insulation resistance tester(tramegger)is a special instrument for measuring insulation resistance.At present,insulation resistance tester can be divided into two kinds:digital type and pointer type.Digital insulation resistance tester has been developed to the intelligent level of digital display.Pointer-type insulation resistance tester can be divided into electronic type and hand-operated type.At present,pointer-type insulation resistance tester is mostly used in the production site.(https://www.daowen.com)
