Testing circuit breakers in medium and high voltage electrical substations is crucial for several reasons. Firstly, it ensures the safety of the equipment and personnel as circuit breakers are designed to protect the system from damage caused by overloads or short circuits. Secondly, regular testing can help identify any potential issues or malfunctions in the breaker’s operation, allowing for timely maintenance or replacement. Lastly, it verifies that the circuit breaker will operate correctly under fault conditions, maintaining the reliability and efficiency of the power system. Therefore, regular testing is a critical aspect of substation management.
