• Perform testing of generator-related panels and circuits at site
• Conduct interface checks between panels
• Commission generators and associated systems
• Execute site tests before and after GT (Gas Turbine) start-up
• Minimum 5 years in testing and commissioning electrical systems for thermal power plants
• Hands-on experience with generator control systems, excitation systems, and protection relays
• Strong understanding of generator main circuit, synchronization, and interlock logic
• Experience in site testing procedures including power receiving, loop checks, interlock, phase relation, load rejection, and performance tests
• Familiarity with grid compliance standards (e.g., NERC, IEEE)

Good to Have

• Commissioning of combined cycle power plants
• Knowledge of Static Frequency Converter (SFC) operation and troubleshooting
• Experience with SCADA/DCS systems integration
• Ability to interpret electrical schematics, wiring diagrams, and logic drawings
• Previous overseas commissioning experience
• English communication skills for technical discussions and reporting
• Ability to work in multicultural teams and adapt to overseas site conditions
• Problem-solving and troubleshooting under time constraints

Job Requirements

At Quest Global, it’s not just what we do but how and why we do it that makes us different.
