An 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/R1min and temperature independent.

Megger_MIT525As well as measuring insulation resistance to 10 TΩ, the Megger MIT525 5-kV Insulation Resistance Tester also offers various diagnostic tests such as Polarisation index, Dielectric Absorption Ratio, Step Voltage, Dielectric discharge and ramp testing.

The rugged case of the Megger MIT525 5-kV Insulation Resistance Tester provides ultimate protection for a portable instrument and a clip-on lead pouch ensures that leads remain with the instrument at all times. The case lid is removable for improved terminal access. IP rating is IP65 with the case closed preventing water/dust ingress. High reliability and safety are built in; the Megger MIT525 5-kV Insulation Resistance Tester is safety rated to CATIV 600 V and is double insulated.

Simplicity of operation is achieved with two rotary switches, and the large backlight display enables multiple results to be displayed simultaneously. 

Megger is one brand you can count on, and Protec offers for rent, lease or purchase, all the electrical testing equipment you need to get the job done.
