In the daily operation of 35 kV substations, adhering to scientifically rigorous operating procedures is essential. These procedures first include regular inspection and maintenance of equipment to ensure all devices are functioning properly. In addition, operators must be familiar with the substation’s operational processes, including transformer start-up, operational monitoring, and shutdown procedures.

In practice, the “transformer oil level” and “temperature alarm” systems should be checked regularly to prevent unexpected faults. Maintenance of the grounding system is also a critical part of the operating procedures, requiring periodic testing of grounding resistance to ensure the safety of both equipment and personnel.

At the same time, all operational data, including current, voltage, and load variations, should be recorded on schedule, providing essential data support for fault diagnosis. Following these procedures not only reduces the frequency of faults but also enhances the overall safety and reliability of the substation.
