• Applies to: [Substation Operations and Maintenance Team]

Procedure

1. Conduct Pre-Shift Equipment Checks: Before commencing operations, perform a visual inspection of all critical substation equipment, including transformers, circuit breakers, and control panels. Verify all indicators are within normal operating ranges and record any anomalies in the daily log [Logbook Name]. (Responsible: Substation Operator)
2. Monitor SCADA System Parameters: Continuously monitor the Supervisory Control and Data Acquisition (SCADA) system for real-time voltage, current, frequency, and power readings. Identify and report any deviations exceeding the established operational limits of [Threshold Value] to the Control Room. (Responsible: Control Room Operator)
3. Execute Switching Operations: Follow approved switching orders [Switching Order ID] for isolating equipment for maintenance or restoring power. Confirm all safety clearances and verify the status of circuit breakers and disconnect switches before and after each operation. (Responsible: Authorized Technician)
4. Perform Routine Maintenance Tasks: Carry out scheduled preventive maintenance activities such as cleaning insulators, checking battery bank electrolyte levels, and tightening electrical connections as per the maintenance schedule [Schedule Reference]. Document all completed tasks and observations. (Responsible: Maintenance Crew Lead)
5. Implement Lockout/Tagout (LOTO) Procedures: Prior to any work on de-energized equipment, apply LOTO devices strictly following the safety protocol [Safety Protocol ID]. Verify zero energy state using a calibrated voltage detector [Detector Type] before allowing personnel to commence work. (Responsible: Authorized Technician)
6. Respond to Alarms and Abnormal Conditions: Investigate the cause of any alarm or abnormal reading from the SCADA system or local equipment indicators. Initiate corrective actions or follow the emergency response plan [Emergency Plan Name] if an incident requires immediate attention. (Responsible: Control Room Operator)
7. Conduct Equipment Testing: Perform periodic diagnostic tests on protective relays, circuit breakers, and transformers according to the testing schedule [Testing Schedule Name]. Analyze test results against manufacturer specifications [Manufacturer Spec ID] and report any discrepancies. (Responsible: Testing Specialist)
8. Update Operational and Maintenance Records: Accurately record all operational activities, maintenance performed, incidents, and test results in the Substation Logbook [Logbook Name] or the Computerized Maintenance Management System (CMMS) [CMMS System Name]. (Responsible: Substation Operator)
9. Report Incidents and Near Misses: Document any equipment failure, operational error, or safety incident using the designated incident reporting form [Form Name] within [Number] hours of occurrence. (Responsible: All Personnel)
