Megger MIT520/2 Resistance Tester Applications
The MIT520/2 is designed for testing the insulation of high-voltage electric equipment. The wide voltage range also allows applications for low-voltage equipment. Generators, motors, transformers, cables and switchgear all require effective maintenance. The test techniques on the instruments provide valuable diagnostic information. The MIT520/2 tests the insulation resistance of:
The MIT520/2 also performs spot tests, step-voltage tests, dielectric discharge tests and dielectric absorption tests for the following applications:
