Megger test is a test conducted to determine the quality of the insulator of devices. This test is actually an insulator test of a device or cable. People often call it megger test is because the technicians often use the insulator test tool with the Megger brand. Though many brands of insulation device tests available on the market, such as Fluke, Hioki, Megger and so forth.
Megger test is also called the Mega Ohm Meter Test, this is because to be accepted the megger test results have to range from mega to mega unit.
So what megger test values can be used for good insulation quality standards? The insulator value or megger result is in good condition if its value is a thousand times the voltage rating of the devices or cables.
