Insulation Resistance Tester, Monitor

A revolutionary new automatic, in-line insulation resistance tester and monitor is now available from Gerhardt`s Inc. The permanently installed system for testing from 500 to 5000 VDC, Meg-Alert, continuously tests winding insulation dielectric strength while the equipment is idle. Current limited DC test output is used to safely detect insulation breakdown and can alarm or lockout equipment. This maintenance protection helps eliminate unscheduled downtime, reduce repair costs, increases staff efficiency and enhances worker safety.
