Understanding Distribution Transformers: Your Electrical System Heart
According to Wikipedia, the distribution transformer or service transformer is a transformer that provides a reduction in the final voltage in the electric power distribution system. This transformer serves to reduce the voltage used in the distribution network to the level that can be used by customers. In other words, distribution transformers are vital components that bridge high -voltage electricity networks with end consumer power needs.
The main functions of the distribution transformer include:
Voltage regulation: Maintaining the output voltage to remain stable and optimal, ensure that electrical equipment operates on peak efficiency and prevent damage due to voltage fluctuations.
Power distribution efficiency: minimizing power losses (loss) that occurs during the electricity distribution process, such as core losses and copper losses (copper losses), thereby increasing overall energy efficiency.
Isolation and Protection: Provide galvanized isolation between the primary and secondary sides, and offers important protection against electrical disorders such as overfoltage and short circuit, which can endanger equipment and safety.
Load flexibility: Able to handle varying load fluctuations throughout the day, ensuring consistent electricity supply despite changing power demand.
