Transformer Insulation Resistance Tester that we offer has an absorption ratio (IR 60 Sec/ IR 15 sec) and polarization index (IR 600 sec/ IR 60 sec), which are calculated and saved automatically. Transformer Insulation Resistance Tester features digital alphanumeric Display and its resistance range is up to 100 G. it operates on different test voltages such as 500V, 1000V, 2500V, 5000V, 10000V. It is suitable for testing generators, HV motors, power capacitors, transformers, cables, and lightening arresters. It is also ideal for site test in EHV substation. Its short circuit current is greater than 5 m A and offers automatic discharge after the test is over. Transformer Insulation Resistance Tester has internal rechargeable battery and charger for heavy duty operations.
