Megger BM5500 5KV Insulation Tester

Description

Electrical insulating materials deteriorate with time leading to breakdowns and costly repair bills. Insulation resistance testers apply a regulated DC voltage across the insulation and measure current flow through it applying Ohm’s law to calculate insulation resistance.

Megger BM5500 is a battery-powered insulation tester with digital and analog arc display, designed for high voltage insulation resistance testing in the maintenance and servicing of cables, rotating plant machinery, transformers, switchgear, and industrial applications.

DC insulation tests are performed at 250 V, 500 V, 1000 V, 2500 V, and 5000 V. Insulation resistance measuring range is 100 k Ω to 1000 G Ω. Automatic discharge for capacitive circuits under test is provided and decaying voltage displayed.

The guard terminal can be used to minimize the effects of surface leakage and hence erroneous measurements when carrying out insulation resistance tests.
