What is an Megger meter or tester used for.?

What is an Megger meter or tester used for? can i use it to test wire insulation? if not what meter can i use?

Meggers works by applying a known DC voltage to a wire for a given period of time too test the resistance of the insulation on that wire or winding. When the voltage is applied you are given the ability to find high resistance shorts. So while the wire or winding may not have a short when you test it without voltage with an ohm meter, the resistance may change when the voltage is applied. Since the current takes the path of least resistance, this is when the short would present itself. Meggers have to be used properly as they apply voltage which can be destructive to the piece of equipment being tested. If you apply too high a voltage, you can destroy the equipment by exceeding the insulation rating of the wire or device. If your equipment is rated for 240v and your Megger is has settings for 300v 600v and 1000v use the 300v setting.
