Order LookupMegohmmeters
Megohmmeters send high-voltage pulses through parts and equipment to measure electrical resistance and identify insulation leaks and shorts. These portable instruments use insulated test leads to establish connections with test objects like cables, wires, transformers, generators, switchgear, and motors. Megohmmeters help electricians, operators, and facility maintenance crews know when insulation has deteriorated and it’s time to replace faulty parts and equipment. They eliminate system downtime, improve safety, and reduce costs.
