FAQs on comprehensive electrical substation maintenance program

electrical substation maintenance program

An electrical grid cannot function properly without operational substations. Issues within the substations can lead to significant power loss and outages throughout the entire grid. This is why various electrical substation maintenance programs exist. Below, we answer some of the commonly asked questions regarding these programs.

 

1. Why is substation maintenance important?


 Substation maintenance is vital for several reasons:

 

-          Reliability: Regular maintenance minimises the risk of unexpected failures in the substation, which can lead to power losses.

 

-          Safety: Comprehensive maintenance ensures the safety of workers and others near the substation by addressing potential hazards promptly.

 

-          Cost savings: Proactive maintenance is more cost-effective than emergency interventions. Addressing issues early prevents them from escalating..

 

 

2. What are the key components of substation maintenance?


 A thorough substation maintenance program typically includes:

 

-          Visual inspections: This involves checking equipment and machinery for visible issues.


-          Electrical testing: Procedures such as insulation resistance tests, circuit breaker tests, and transformer oil analysis help gauge the substation's health.


-          Cleaning: Keeping insulators and other components clean prevents contamination and enhances overall performance.


-          Lubrication: Applying lubricants to moving parts reduces wear caused by friction.


-          Control system maintenance: This ensures the proper functioning of control systems, relays, and communication equipment.

 

3. How often should substation maintenance be conducted?


 The frequency of substation maintenance varies based on factors like equipment age, weather conditions, and the substation's criticality. However, common schedules include:

 

-          Annual inspections: Visual inspections and basic tests conducted once every year.

 

-          Biennial or triennial maintenance: In-depth analysis and tests are conducted once every two or three years.

 

-          Emergency and corrective maintenance: Sudden malfunctions or issues can result in corrective maintenance.

 

4. What are the risks of neglecting substation maintenance?


 Neglecting substation maintenance poses several risks, which include:

 

-          Equipment failure: Equipment failure is one of the most common results when maintenance is neglected. In such cases, the entire grid may face significant downtimes.

 

-          Power outages: Power losses can occur as a result of equipment failure. This can inconvenience the general populace and even cause major economic losses for businesses.

 

-          Safety hazards: Equipment related to substations can malfunction and pose a safety risk for people working in and around the substation. Accidents and injuries can also occur as a result.

 

5. How does substation maintenance contribute to grid resilience?


 Grid resilience refers to the characteristics of well-maintained substations to be resilient to voltage fluctuations and power outage. In case of highly maintained substations, power outages are less likely to occur. In case there is a loss of power, the substations generally recover sooner.
