What is Megger Test and How is it Performed

WebSpot-reading test: You can use this method for testing house wiring or any electric panel with short capacitance. Temperature and humidity may affect the readings of this test. To perform this test, just connect your megger across the testing insulation. Now, apply the required voltage for a short period (approx. 60 seconds). WebA megger is used to check the insulation resistance of the electrical equipment. So we can use a megger to test a motor, generator winding, cable, etc. A megger tests a wire by applying a high voltage DC to it for a certain time period so that the insulation quality can be determined. A megger is comprised of a DC generator and an Ohm meter.
