Megger test
On the whole megger testing is non destructive. What happens is a DC voltage is applied to the device or winding under test. It is an insulation test to see is the insulation has been injured in any way to cause a short circuit when normal power is applied to it. On my megger there are 3 ranges 300V, 750V, and 1000 volts. Applying the proper voltage is essential to not damaging the device you are testing. Working voltages up to 240 volts should use the 300 range. Working voltages up to 600 volts use the 750 volt range and working voltages above 600 use the 1000 volt range. As you can see if you used the 1000 volt range on a device that had a working voltage of say 24 volts you could damage the insulation just by testing it. So meggering a device is non destructive if you use the tester as its instructions tell you to.

What is the voltage used for megger check of aircraft looms?
I did them with a 1,000 volt megger .
What is the required resistance in mega ohm when performing megger?
Normally the megger should be selected based on the following criteria. 1.Voltage rating of the megger 2.Range of the megger value 3.Manual - Hand operated analogue type 4.Auto- Digital Megger To measure the insualtion resistance of Motor (LV Motors) Up to 500 V/1000 V Megger is sufficient To measure the insualtion resistance of Motor (HV Motors) Up to 5000 V can be choosen Normaly the range starts from 0.5 to Infinity meg value in the analogue However in digital the based on the least count /range of the instrument we can able to measure the insualtion value.
What is the g in a megger test?
It is the terminal on the megger that the ground cable connect to when testing a device to ground.
