See Chinese contents: GB/T 22719.2-2008 GB/T 22719.2-2008: Interturn insulation of random-wound winding for AC low-voltage electrical machines -- Part 2: Test limits
This Part of GB/T 22719 specifies the interturn insulation test of random-wound winding for AC electrical machines - test parameters, test limits and the allowable value of the test waveforms difference quantity when doing the automatic test discrimination. This Part applies to random-wound winding interturn insulation test for the 3-phase or singlephase AC electrical machines of which the nominal voltage is no more than 1140V.
