Aug 6, · To perform an insulation test (Megger test) on a 3-phase V asynchronous squirrel cage motor, follow these steps: Disconnect the motor from the power source. Megger Missing: Pdf. Oct 30, · Use a standard multimeter to check phase-to-phase resistance (ohms) on all three phases. Note: All readings should be approximately the same and will vary depending on the Missing: Pdf. Use a Megger with applied test voltage suitable for the motor in question as follows: Low Voltage Motors ( VAC) use only a Volt megger. Medium Voltage Motors ( VAC) Missing: Pdf.The document outlines the basic steps to ascertain the health of a three-phase AC motor: (1) General inspections such as checking for damage and testing shaft rotation. (2) Earth continuity and resistance test and power supply test to check for proper voltage. The Megger insulation tester is a small, portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. For good insulation, the resistance usually reads in the megohm range. The Megger insulation tester is essentially a high-range resistance meter (ohmmeter) with a built-in direct-current generator.
