How to measure the insulation of generator?
400V generator with 500V shaking table, 6300V generator with 2500V shake meter, measuring insulation value, respectively, winding to ground, interphase insulation. Rotor winding with 500V shaking table. Minimum requirement is per kilovolt - 0.1M Europe
But now a general point of power plant are electronic shake table, do not need to shake, the same is set up according to the basic parameters on the surface, the shaking table, can be said to be a fool, such as the measurement of grounding resistance, grounding E G (P) is connected to the device. Finally, just press a button can be measured after.60 seconds can be measured to 15 seconds and 60 seconds. The resistance resistance will automatically give you calculate the absorption ratio, and print it out!
