Designation: Generator Installation, Commissioning & Overhauling Engineer Role Purpose

Responsible for the installation, alignment, testing, hydrogen gas handling, commissioning, maintenance, and overhauling of large turbine generators in thermal, combined cycle, and industrial power plants. Ensure secure and reliable operation of generator systems in accordance with OEM specifications, quality standards, and safety requirements.

Key Responsibilities 1. Generator Installation & Erection

Supervise generator stator, rotor, bearing, seal oil system, and auxiliary equipment installation.
Verify foundation readiness, generator alignment, and coupling alignment with turbine.
Monitor installation of excitation systems, cooling systems, and hydrogen systems.
Ensure compliance with OEM erection procedures and quality requirements.
Coordinate with contractors, vendors, and customer representatives during installation activities.

2. Hydrogen Filling and Purging Operations

Prepare procedures for hydrogen charging and purging of generators.




Conduct CO? purging before hydrogen filling and vice versa during shutdown.
Monitor hydrogen purity, dew point, pressure, and leakage rates.
Ensure compliance with safety procedures for handling hydrogen and carbon dioxide.
Maintain records of gas consumption, purity, and operational parameters.

3. Generator Commissioning

Perform pre-commissioning checks and system readiness verification.
Conduct insulation resistance (IR), polarization index (PI), winding resistance, and other electrical tests.
Verify operation of protection systems, seal oil systems, excitation systems, and cooling systems.
Support no-load, synchronization, and full-load testing activities.
Prepare commissioning reports and handover documentation.

4. Generator Overhauling & Maintenance

Plan and execute generator major and minor overhauls.
Supervise rotor withdrawal and insertion activities.
Inspect stator winding, rotor winding, retaining rings, bearings, seals, and
