Perform accurate insulation resistance measurements in tough, high noise environments 5 kV, 10 kV, and 15 kV high performance diagnostic insulation testers for power utilities and service companies The S1-568, S1-1068, and S1-1568 insulation resistance testers from Megger come with class-leading noise rejection of 8 mA – twice that of most comparable instruments – and enhanced software filtering that has four user-selectable options. These DC insulation resistance testers come in 5 kV, 10 kV, and 15 kV and deliver dependable results in even the most severe of electrical environments, including high voltage transmission and distribution substations. The performance of these groundbreaking instruments has been exhaustively proven in the laboratory and, more importantly, has been convincingly demonstrated in the field. Accurate and consistent results were, for example, obtained in a working 765 kV substation where no other insulation tester had been able to operate successfully. Megger’s S1 series of insulation testers are available in three models: • The S1-568 tests at up to 5 kV and can measure insulation resistance up to 15 TΩ • The S1-1068 operates at up to 10 kV and measures up to 35 TΩ • The S1-1568 has 15 kV capability and measures up to 35 TΩ All models have a high short-circuit current of 6 mA to ensure rapid charging of items under test. The S1-568 and S1-1068 have a CAT IV 600 V safety rating, at altitudes up to 3,000 m, with the S1-1568 having CAT IV 1000 V to 4,000 m, in line with IEC 61010.
