查询词典 short-pitch winding

Since it is usually necessary to de-energize the winding before measuring R H, and the resistance of the coil may change rapidly as the temperature decreases, it may be necessary to determine the value of R H at the end of the test by taking several resistance measurements at short intervals, beginning as quickly as possible after the instant of shutdown.
