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 …

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 …

Sep 8, 2009 · To talk about this you need to give us more technical details, types of equipment and voltage classes, test methods you are using for megger and hipot tests. No trees were killed in the …

Aug 17, 2015 · A megger is simply a "megohm meter" and it only measures insulation resistance, at higher values than a regular ohm meter. Generally a regular DMM operates at 9VDC on the ohm …

Aug 24, 2012 · A megger is normally used to test insulation leakage to GROUND. If testing "T" to "T" lead, the resistance should be near zero as all of the windings are connected together internal to the …

Jan 7, 2018 · So I was taking some megger readings on some underground the other day, and what I noticed was that my resistance reading would increase every time I increased the voltage. 100VDC - …

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 …

Jun 29, 2007 · In commercial, use it to megger out a new feeder you just pulled in. Measure each wire to each of the other wires, and each wire to the metal conduit. You want basically infinity readings. If …

Jan 8, 2013 · megger test Megger or insulation testing can be done for 1 min or a 10 min. I've done it this way for years on 480 and 4160 volt motors an transfomers 11,000 volt on up at the Powerplant …
