Overview of Megger Test

A megger is basically an ohm meter on steroids.  They both test for the insulation properties of electrical wiring, motor windings, and high power antennae mounts.   However, meggers use a much higher voltage to identify resistances.   Megger Testing is harmless to the equipment since a DC voltage is applied to the device that is being tested. The test is simply to show if there is any knick, laceration, or hole in the insulation.  Megger settings range from 300V to 10kV.  ITI’s team of certified electricians possesses the knowledge to use the proper voltage setting on a wide variety of electrical equipment.   Otherwise, there is the potential of damaging the equipment being tested.  Megger tests show leakages in current and its specific location by identify areas where there are damages to the insulation.  It is also possible to detect leaks on bad motors, transformers, generators, and other equipment found in substations.

How to Interpret Results

Cables need to be replaced if they show resistances under 1.00, cables that show readings between 1.00 and 1.35 are functional, and cables that show readings higher than 1.35 are fully functional.  Resistances should increase after each test since heat dissipating through the cables from the test increases resistance.

Benefits of Megger Testing
