Step Down Pad Mounted Transformer Production Process

Dry type pad mounted transformer 

three phase Step-down pad mounted transformer maintenance:

1. Check the power cord

Regularly check the power cord of the 3 phase step-down pad transformer to ensure that the connection is safe and stable. In addition, check whether the power cord has any signs of damage or aging, and replace it if necessary.

2. Check the cooling system

The cooling system is a key component of the 3 phase step-down pad transformer. Regularly check the operation of the cooling system to ensure that the coolant flows normally. If the coolant is found to be short or deteriorated, please replace or add new coolant in time.

3. Accurately measure voltage and current

Regularly use special instruments to measure the voltage and current of the 3 phase step-down pad transformer to ensure that the output voltage and current meet the design requirements. If there is any deviation, the relevant parts should be adjusted or replaced in time.
