MEGGER MIT1525 15KV Insulation Resistance Tester

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.

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 .

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.

Features :

Insulation resistance up to 30 TΩ @ 10 kV enables installation testing and long-term trending of higher value apparatus, typically above 1 TΩ.
High altitude operation up to 3000 m while maintaining CATIV 1000 V (15 kV).
5% accuracy all the way up to 3 TΩ @ 15 kV ensures highest accuracy where it matters most.
IR, timed IR, DAR, PI, DD, SV and ramp tests maximize diagnostic testing capability.
3 mA short circuit current with unique max power regulations technology ensures maximum transfer whatever the load until selected voltage is reached.
Noise filter rejects up to 6 mA (15 kV) noise for effective operation in electrically noisy environments.
Li-ion battery allows up to 6 hrs continuous testing @ 5 kV with a 100 MΩ load; battery meets IEC 62133.
Dedicated voltmeter function (30 V to 660 V) allows the user to check for induced volages.
Smaller size and lighter weight allows easier transport and use without compromising performance.
Unique dual case design allows for fire-retardant protection while maintaining ruggedness.
