When is it not allowed to adjust the tap changer of the transformer on-load voltage regulating device? Answered by the best transformer factory in China

1) When the transformer is overloaded (except in special cases) 2) When the light gas protection of the on-load voltage 调节设备 frequently generates signals. 3) When there is no oil in the oil standard of the on-load pressure regulating device. 4) When the number of pressure adjustments exceeds the specified time. 5) When the pressure regulating device is abnormal.
