Product Details

Megger MIT1525 15kV Insulation Resistance Tester

The Megger MIT1525 completes Megger’s high voltage range of MIT insulation resistance testers. Outputting voltages of up to 15kV, the MIT1525 can produce a resistance value up to a massive 30TΩ in addition to timed testing, polarisation index (PI), dielectric absorption ratio (DAR), step voltage, dielectric discharge and ramp testing.

The instrument can also test in step voltages which is necessary to ensure that insulation and cables within an installation can withstand the normal day-to-day voltage spikes that, perhaps, a motor typically sees during operation. If a DC Step-Voltage Test is not performed, the operator cannot be assured that a motor will start and operate without failing in service. The MIT1525 can output in 25V steps between 1kV and 5kV and 50V steps between 5kV and 15kV.

Test results can be stored within an advanced internal memory complete with time/date stamping; results can be recalled at a later date for analysis on screen. Although the internal memory allows for five and a half hours of measurements taken at five second intervals, they can also be viewed in live-time should the insulation resistance tester be connected to a PC/Laptop via USB running the supplied Megger PowerDB Lite software package.

Simplistic operation is ensured with two rotary switches and a large, back-lit display which enables resistance, voltage, leakage current, capacitance, battery level and test time to be displayed simultaneously.

The MIT1525 features a dual case design which protects the unit from knocks and drops, but it also fire retardant. When the instrument lid is closed, the seal also offers moisture and dust ingress protection rated to IP65. The MIT1525 is supplied with a calibration certificate as standard.

Why Test for insulation Resistance?

Electrical insulation can be affected over time by temperature, current flow, physical damage, chemical damage and environmental conditions to name a few. Both the reliability and the safety of an electrical installation can become an unwanted issue should insulation resistance values not be tested regularly and monitored.
