Insulation Resistance (IR) testing cables, transformers, motors/generators, circuit breakers and bushings look to
Megger’s DC insulation testers.
The Megger MIT525 5-kV Insulation Resistance Tester and the Megger MIT1025 10-kV Insulation Resistance Tester have a full suite of test modes as well as on-board memory and the ability to stream data/download data to a PC/laptop.
Instrument productivity is a focus of the MIT range which offers rapid charge batteries and operation from an AC source if the batteries are flat. Rapid charge batteries enable > 60 minutes testing after a 30 minute charge.
Safety rating is not compromised on the MIT525 and the MIT1025 range with all terminals safety rated to CATIV 600 V to 3000 m (5 kV, 10 kV or CATIV 1000 V to 3000 m (15 kV). A range of 5 kV and 10 kV test leads are available plus dedicated 15 kV test leads which are double insulated with clips designed for 15 kV creepage paths.
