Capable of providing accurate measurements up to 10 TΩ for 5 kV versions and 20 TΩ for 10 kV versions and having facilities for IR, IR(t), PI, DAR, DD, SV and ramp tests, Megger’s new high-voltage insulation resistance testers (IRTs) offer versatility in a compact, rugged and light unit that weighs almost half as much as its predecessors. The instruments also provide enhanced productivity – they can be used from an AC source even when their internal rechargeable battery is fully discharged – and they are capable of delivering dependable results even in noisy electrical environments, such as electricity substations, with noise levels up to 3 mA. Megger’s new IRTs are available in three versions: the MIT515 5 kV (an entry-level 5 kV test set); the MIT 525 5 kW insulation resistance tester (also a 5 kV unit, adds facilities for dielectric discharge (DD), step voltage (SV) and ramp diagnostic testing; and the MIT 1025 10 kV insulation resistance tester (with the same facilities as the MIT525, but a 10 kV unit).
