Offering CAT IV 600 V, the Megger MIT1025 (1001-944) is a compact, light 10 kV insulation resistance tester for the diagnostic testing and maintenance of high voltage electrical equipment. Enclosed in a tough case it is both smaller and lighter than its predecessor making it even easier to carry and store.

As well as measuring insulation resistance to 20 Teraohms, the MIT1025 also offers various diagnostic tests such as Polarization index, Dielectric Absorption Ratio, Step Voltage, Dielectric discharge and ramp testing.

APPLICATIONS
The Insulation Resistance (IR) test is a quantitative test, which indicates the effectiveness of a product’s electrical insulation. Applications include cables, transformers, motors / generators, circuit breakers and bushings. Common insulation tests are the “spot test”, a 1 minute IR test and a 10 minute Polarisation Index (PI) test, where PI is the ratio R10min / R1minand is temperature independent.
