Megger’s new high-voltage insulation resistance testers (IRTs) offer exceptional versatility in a compact, rugged and light unit that weighs little more than half as much as its predecessors. Capable of providing accurate measurements up to 10 T? for 5 kV versions and 20 T? for 10 kV versions and having facilities for automatic timed IR tests and more advanced diagnostic tests; PI, DAR, DD, SV and ramp tests.
The new 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 is an entry-level 5 kV test set which offers insulation resistance (IR), timed insulation resistance (IR(t)), dielectric absorption ratio (DAR) and polarisation index (PI) test modes.
