Endorsement and Calculation of structural support will be to be supplied.
How does a substation protect a power system?
It transforms the voltage from low to high or the reverse. Since substation is so important in the power system, and the cost to build it is also expensive, it is necessary to have adequate protection method to protect it. This project focuses on one of the 22kV/6.6kV substation which is under construction at PSA Pasir Panjang Terminal.
How does a circuit breaker work?
Circuit breakers form part of a broader substation protection and control system that includes current transformers, voltage transformers, and digital protection relays. When a relay detects an abnormality, it sends a signal to the breaker to open, thereby isolating the faulty section.
Why is a circuit breaker important?
A circuit breaker is a crucial component of your electrical system that protects your home or business from electrical overloads and short circuits. Over time, circuit breakers can wear out or become outdated, leading to issues like: If your breaker trips often, it may be unable to handle your property's electrical load.
