- Preparation of control and protection logic, schematic diagrams, interlocking schemes, and panel GA drawings.
Transformer Design Understanding:
- Working knowledge of power transformer sizing, vector group selection, impedance, cooling type, and loss analysis.
- Evaluation of transformer data sheets and technical specifications.
Cable Engineering:
- Voltage drop calculations, cable derating factors, and cable loss analysis across HT and LT networks.
- Cable sizing and routing design for underground and overhead layouts in power plant applications.
(Bonus) Solar PV Design Exposure:
- Experience with inverter selection, string sizing, DC cable layouts, and grid integration is a plus.
- Familiarity with SCADA, monitoring systems, and SLDC interfacing is desirable.
Qualifications & Skills:
- B.E./B.Tech/M.Tech in Electrical Engineering from a recognized institute.
- 9-12 years of relevant experience in electrical system design for utility-scale power projects.
- Proficient in AutoCAD, ETAP/PowerWorld/Digsilent, and Microsoft Excel.
- Deep understanding of Indian grid codes (CEA regulations), IS/IEC standards, and DISCOM interconnection guidelines.
- Strong analytical and engineering fundamentals.
What We Are Looking For:
- Passion for core electrical engineering and clean energy.
- Willingness to work on end-to-end engineering, from concept to commissioning.
- High attention to detail, structured thinking, and a problem-solving mindset.
- Ability to collaborate with internal teams and external stakeholders (consultants, vendors, DISCOMs).
Preferred (Not Mandatory):
- Prior experience in solar project engineering, though not required.
- Exposure to substation construction or utility coordination.
- Hands-on knowledge of SCADA/data acquisition systems.
