Megger S1-1068 10kV High Performance Diagnostic Insulation Tester

The S1-1068 high performance insulation tester has been designed to make accurate stable measurements in noisy environments such as 765kV substations, with remote operation for additional safety provided in high energy locations.

Regular insulation resistance testing is one of the most cost effective, non-destructive methods of identifying ageing in electrical equipment. With over 60% of equipment failures being ascribed to insulation breakdown, it is a key area to monitor. Diagnostic DC testing is probably the easiest and most convenient method of achieving this due to the small size and weight of the equipment.

With a full 8 mA of noise rejection and 4 levels of filtering the fast charging S1-1068 obtains meaningful results in extremely hostile environments. Offering the full gamut of automatic insulation tests, IR, timed IR, polarisation index (PI), dielectric absorption ratio (DAR), Step Voltage, Dielectric Discharge and ramp, the S1-1068 allows the operator to control the test remotely from a computer using the 10 kV isolated USB port, to store the date and time stamped results on board or to download them is real time using Bluetooth. This is the perfect tester for the itinerant contractor as it will give results in any electrical environment.


Which maintenance teams will benefit from the Megger S1-1068?

  • Power utilities and service companies working in generation, transmission and distribution markets
  • Testing electrical insulation: Cables, transformers, motors/generators, circuit breakers, bushings
