69kv 66kV Power Transformer
Power transformers are used for the following applications:
- Power generation and distribution.
- It is increasing the voltage of an electrical supply to transmit electricity over long distances.
- Decreasing the voltage of an electrical supply to make electricity safe for use in homes and businesses.
- Isolating two electrical circuits from each other to safeguard sensitive electronic equipment.
- Providing sufficient power to electronic equipment that requires a lot of electricity.
- Sustaining the voltage of an electrical supply during power surges and brownouts.
- Converting the voltage of an electrical supply from one country to another.
- Reducing power losses during the transmission and distribution of electricity.
- Used in cases where the load is required to have a different voltage than the supply.
