2 After the transformer is put into operation, it is forbidden to touch the main body of the transformer to prevent accidents. It is strictly forbidden to regulate the voltage of the non-excitation voltage regulating transformer.
3 Before the high voltage test of the transformer, the temperature sensor cable should be removed from the temperature control box to prevent amage to the temperature control box. All temperature sensors, sensing lines, and secondary control lines must not be in contact with the live parts of the transformer.
