Electrical Reliability Engineer (High Voltage)

Entity: GEGL

Position:
Electrical Reliability Engineer (High Voltage)

Division / Department:
Operations & Maintenance (OM) / Power (POW)

Location:

Several Locations, Western Region, Ghana (West Africa)

Report Directly to:
Electrical Reliability Superintendent

Subordinate:
Assistant Electrical Reliability Engineer

Designation Level: Sectional Head

The Electrical Reliability Engineer (High Voltage) is responsible for identifying, assessing, and mitigating reliability risks associated with all high-voltage (HV) electrical assets and distribution systems within the CCGT plant. The role ensures the availability, integrity, and optimal performance of critical HV equipment, including power transformers, switch gear, transmission and distribution lines, protection and control systems, and high-energy distribution networks, through effective condition monitoring, diagnostics, and reliability-centered maintenance strategies.

This position plays a key role in maintaining operational excellence, minimizing unplanned outages, and safeguarding the long-term reliability, safety, and performance of the plant’s high-voltage electrical infrastructure.

• Support the EPC Project Team during Construction, Installation, and Commissioning of all HV electrical systems.
• Assist in reviewing Authorized For Construction drawings (AFCs), Single Line Diagrams (SLDs), protection schemes, cable routing, and commissioning checklists.
• Review redline and as‑Built drawings to verify accuracy and compliance with HV engineering standards.
• Provide technical oversight during the installation of HV components such as transformers, HV switch gear, breakers, isolators, and grounding systems.
• Recommend improvements to the HSE team to enhance electrical safety practices specific to HV energization and isolation.
• Support management of warranty claims and punch list items for HV equipment during and after commissioning.
• Ensure adherence to Quality Assurance and Quality Control (QAQC) for all HV installations, testing, and energization processes.

• Ensure the reliability, availability, and maintainability of high-voltage electrical installations by supporting the Electrical Reliability Superintendent in implementing Life Cycle Asset Management (LCAM) for the following assets:

• HV transformers (power and auxiliary)
• HV, MV, and LV switch gear
• Circuit breakers, disconnect switches, and isolators
• Protection relays and schemes
• Busbars, insulators, and HV cable systems
• Neutral grounding resistors
• Lightning and surge protection systems
• Motors, generators, and auxiliary power distribution equipment
• Electrical controls and instrumentation associated with HV systems
• Cooling systems and transformer auxiliaries

• Design, develop, monitor, and refine maintenance plans that include:

• Predictive, proactive, preventive, and corrective maintenance tasks
• Effective use of diagnostic tools such as DGA, partial discharge testing, thermography, insulation resistance, tan delta, and contact resistance testing
• Optimized utilization of the Computerized Maintenance Management System (CMMS/CCMS)

• Provide input to HV electrical risk management plans addressing reliability‑related risks such as insulation degradation, transformer failure, circuit breaker misoperation, and protection malfunctions.
• Propose engineering solutions to chronic or repetitive HV failures through:

• Root Cause Analysis (RCA / RCFA)
• Reliability modeling and prediction
• Weibull analysis
• Fault Tree Analysis
• Statistical process control
• Failure Reporting, Analysis & Corrective Action System (FRACAS)
• Six Sigma (6σ) methodology

• Collaborate with the Operations Team to analyze HV electrical asset performance, including:

• Equipment loading and thermal performance
• Transformer efficiency and winding temperatures
• Breaker/trip frequency and reliability trends
• Overall equipment effectiveness (OEE)
• Remaining useful life (RUL) of HV assets
• Electrical losses, operational conditions, and cost impacts

• Execute predictive and preventive maintenance to prevent catastrophic HV failures and reduce unplanned shutdowns.
