The latest in the range of megger HV insulation testers, the Megger MIT1525 15kV insulation tester has a top end specification. It has a full suite of test modes, advanced memory with time/date stamp and the ability to record temperature (measured with independent thermometer) and on-board storage with a capacity to log up to 5.5 hours of data saved every 5 seconds. Downloading of saved results, logs and real-time streaming of results is possible via a USB cable interface.

The Megger MIT1525 15kV DC insulation testers are equally well suited for motor / generator production and repair as they are for low and medium voltage substation use. Transformer OEMs and repairers will benefit from the 15 kV test voltage and the extensive capabilities of the MIT1525.

As well as measuring insulation resistance to 30 TΩ, the Megger MIT1525 also offers various diagnostic tests such as Polarisation index, Dielectric Absorption Ratio, Step Voltage, Dielectric discharge and ramp testing.  It benefits from the Megger dual case construction, tough on the outside and fire retardant on the inside.
