About // Who We Are

MegAlert – The only automatic permanently installed “True Dielectric” Insulation Resistance Testers and Monitors with 500-5000 VDC test outputs.

MegAlert manufactures the MotorGuard and GenGuard patented testing and protection systems designed to detect insulation breakdown in critical motors and generators. The system senses when the motor or generator is offline and then performs a continuous dielectric test on the winding insulation until the equipment is started again.
