Electrical Engineer (Switchyard/Substation) Shift Maintenance Engineer

Job Description

Key Responsibilities: 1 Switchyard Operation & Monitoring: Perform routine monitoring of all switchyard equipment (Transformers, Circuit Breakers, CTs, PTs, Isolators, Reactors, Busbars, etc.). Execute switching operations for energization/de-energization of transmission lines, transformers, and other equipment as per the Load Dispatch Center (LDC) schedule. Ensure voltage, frequency, and load parameters remain within permissible limits. Operate GIS (Gas-Insulated Switchgear) & AIS (Air-Insulated Switchgear) substations . 2 Fault Handling & Emergency Response: Detect and analyze faults, tripping events, and abnormal conditions in switchyard operations. Coordinate with Grid Operators (SLDC/RLDC/NLDC) and Maintenance teams for fault rectification. Respond to blackouts, grid disturbances, or equipment failures and take corrective actions. Maintain proper switching sequence & safety procedures during emergency restoration. 3 SCADA & Substation Automation: Monitor real-time power flow, alarms, and event logs using SCADA/HMI systems. Perform remote/local operation of switchgear, isolators, and circuit breakers . Troubleshoot SCADA communication issues and coordinate with the automation team . 4 Permit to Work (PTW) & Safety Compliance: Issue and verify Permit to Work (PTW), Lockout-Tagout (LOTO) procedures for maintenance activities. Ensure adherence to safety protocols, grounding procedures, and electrical isolation procedures . Conduct safety checks before and after maintenance work on equipment. 5 Reporting & Documentation: Maintain shift logs, event reports, switching operation records, and relay tripping reports . Record voltage, current, frequency, and load conditions in daily shift reports. Generate reports on load flow, transformer loading, reactive power compensation, and outage analysis . Technical Knowledge: Switchyard Equipment Operation (400kV/220kV/132kV Transformers, CBs, CTs, PTs, Reactors, etc.) Switching & Interlocking Procedures, Load Dispatch Coordination SCADA, HMI, RTU, and Substation Automation (IEC 61850, MODBUS, DNP3) Grid Code Compliance & Permit to Work (PTW) Procedures Fault Handling, Tripping Analysis, and Protection Relay Coordination Certifications: Electrical Safety, Grid Operation & Power System Protection (Preferred). Software Skills: SCADA/HMI Operation, Siemens DIGSI, GE EnerVista, MiCOM S1 Agile. Key Traits: Attention to detail, quick decision-making, troubleshooting expertise, and shift flexibility .
