If your organization runs with the support of a substation, periodic maintenance will be definitely required. Much like with cars or any motor vehicle, a range of problems can affect your substation after a point in time, especially in terms of reliability and performance. If these issues are overlooked, you may end up facing breakdowns and even safety issues, which aren't only expensive, but can be dangerous for people.
Substations are the most important part of any electrical generation, transmission, and distribution system. Substations may include transformers to alter voltage levels between high transmission voltages and lower transmission voltages, or somewhere in between of two different transmission voltages. Generally, substation are unattended and remotely supervised and controlled.
Substation maintenance is a process of periodic and planned inspection, repair, and replacement of all switchgears, structures, and ancillary equipment in substation installations. In other words, substation maintenance is routine preventative checks and actions carried out to ensure substations are kept in good working order. The typical process involves a series of strict visual and physical inspections and actions carried out in clusters.
Circuit breakers and transformers are some of the most important components in a substation. These components experience wear and tear with time and continuous use, hence regular maintenance is done to prevent any malfunctions. Circuit breakers are tested and analyzed to identify the possibility of anomalous operations. Some of the parameters to be checked are poles synchronism, open and close timing, coil condition, and contact resistance. Another thing to look at are the transformers since they play a critical role in substation operations. Transformers tend to experience tremendous thermal stress, hence the need for regular testing too.
A secondary test is conducted as a "safety" to the primary test. The objective is to ensure that the established protection scheme delivers. Areas for assessment for the secondary test are relays, wiring, and protection panels. Overcurrent testing, distant testing, frequency testing, voltage protections, and reclose schemes are also looked into. To recap, much like any other machinery, substations require periodic maintenance to keep it healthy and in good working condition. Substation maintenance involves visual and physical inspections that’s done in two phases. These inspections ensure that wear-and-tear components of the substation are taken care of, and that operations will run smoothly.

In the mid to late 1980s, utility companies first began using infrared scanning inspection to monitor condition of their substations.
While many people pay little attention to it, electrical safety in the workplace is important because of the many types of hazards that could set off some serious damage when left neglected.
