What is a primary function of maintenance in substations?

The primary function of maintenance in substations is to ensure reliability and prevent failures. Maintenance activities are crucial for keeping the equipment operational and minimizing the risk of unexpected outages, which can significantly affect the electricity supply. By regularly inspecting, testing, and servicing equipment such as transformers, circuit breakers, and relays, maintenance practices help identify potential issues before they lead to serious problems or equipment failure.

This proactive approach is essential for maintaining the overall performance and safety of the substation. It ensures that all systems operate as intended, thereby contributing to the stability and reliability of the electrical grid, which is fundamental to meeting the demands of consumers and businesses alike.
