WebApr 7, 2024 · The purpose is to find resistance between those two points where normally there should be infinite resistance. The start and run windings are connected together, so a megaohmmeter wouldn't measure any differently than an ohmmeter since the resistance between those two is usually no more than 10 ohms. WebJul 19, 2016 · Theoretically voltage difference between neutral and earth will be zero, but practically it will be 2 to 4 AC volts. If you get closer than zero voltage you are having proper earthing. And also measure the voltage between phase and Earth. It should give the more or less same value which is measured between phase and neutral.
