Acceptable motor megger readings. Megger results are consistent on 500 and 1000 volt tests.
Acceptable motor megger readings But what you’re really asking is – how can you run an insulation resistance The Megger insulation tester is a small, portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. . Aug 10, 2023 · What are acceptable megger readings? Resolution: Hermetic compressor motors should have megohm readings at least equal to 1000 ohms for every applied volt. The acceptable Megger reading for a motor’s insulation resistance can vary depending on factors such as the motor’s type, size, age, and operating conditions. Plus, we’re flattered that you’re throwing around our name so much, so we can’t complain. Would it be acceptable to connect the motor leads to ground for a few minutes after the test to make sure there is no built up voltage. The acceptable Megger reading for a motor primarily depends on its voltage rating. These readings indicate that the insulation is adequate and the motor should operate without any significant Jan 9, 2010 · Readings vary from >4000 Megs down to tens of thousand of ohms. Example: 460 volt compressor should have resistance to ground of at least 460,000 ohms; Megger readings should also be stable from year to year and not show any significant change Dec 17, 2020 · Well, if we’re nit-picking, technically speaking, you can’t ‘Megger’ a motor. Dec 28, 2013 · I suspect the readings might be artificially low but would this be a decent indication of the motor’s health if the readings were normal? Last question, this meter does not have a discharge switch. For good insulation, the resistance usually reads in the megohm range. Megger is a registered trademark, not a verb, but we get it – old habits die hard. Oct 30, 2023 · Acceptable Megger Readings. With my background in aviation and the 100 MegOhm go/no-go rule, this has worked for 25 years. Insulation resistance values are typically measured in ohms (Ω), megohms (MΩ), or gigohms (GΩ) for high-resistance values. Megger results are consistent on 500 and 1000 volt tests. Typically, for low-voltage motors (up to 1,000 volts), readings between 50 to 100 megaohms (MΩ) are considered satisfactory. The Megger insulation tester is essentially a high-range resistance meter (ohmmeter) with a built-in direct-current generator. xcyfqjxjghoxwcsywnalxfsewhxubfwxcbkupcpnffncrxrpocvq
