Jan 14, 2009 · A megger is used to test the integrity of insulation. If you are testing a motor circuit wired to a MCC bucket or a VFD; Open the breaker in the bucket or isolated the VFD. Always test your …

Dec 23, 2010 · From what I've read here, it seems most like the fluke 1507/1589. The only knock on those flukes are their inability to do accurate pi/dar tests. Type in megger in the search function and …

Aug 17, 2015 · A megger (or sometimes meggar) is often used as an alternate term for an insulation tester - a circuit tester which puts a very high voltage at a very low current across two conductors to …

Feb 25, 2012 · DO NOT MEGGER ANYTHING CONNECTED TO A VFD! I agree that adding a disconnect would be a good idea as I assume the megger test is a preventive maintenance …

Jul 9, 2011 · What should the ohms be going from ground to phase on a digital megger? For a good motor should it read around what (400megaohms)? When the motor is bad it should read 0 ohms to …

Aug 2, 2008 · Megger readings that do not stabilize, but fluctuate are indicative of moisture in or on the conductors and should be investigated. Sometimes this reading will continue to climb as the moisture …

Apr 7, 2010 · megger tested motor leads at VFD ( VFD disconnected from motor leads) motor/pump submerged in tank VFD - Motor distance aprox:40' 1 splice in motor wires splice submerged wire …

Sep 19, 2015 · I've never seen anyone hipot 600V cables. A megger is a megohmeter, measures insulation resistance. A hipot tester basically works the same way, but measures leakage current. If …

Jul 29, 2021 · I have looked through a bunch of posts regarding megger testing and not seeing what I am looking for. I am looking for a “standard” that says this XX MΩ reading is a “pass” and this XX MΩ …

Dec 29, 2013 · You can damage this equipment or at a minimum get false readings. Typically start with the lowest voltage your megger has, starting at 50, 100 or 250 VDC will minimize any chance of …
