Job summary

Elegrow Technology Pvt. Ltd. seeks an experienced electrical commissioning professional to perform pre-commissioning checks, insulation resistance tests, CT/PT and relay testing for substation and industrial power systems.

You will conduct transformer and switchgear tests, support solar PV testing, and assist in SCADA/RTU and ELV system commissioning. The role requires travel to site deployments, strong documentation skills, and familiarity with IS/IEC standards.

Qualifications

• Experience with pre-commissioning checks and electrical testing.
• Familiarity with IS/IEC testing standards.

Responsibilities

• Conduct pre-commissioning checks including visual inspection, torque verification, cable dressing/termination checks, labelling and tagging verification.
• Perform insulation resistance (IR/megger), continuity, earth resistance, and polarity/phase sequence testing.
• Execute CT/PT ratio and polarity testing, and protection relay testing for substation and industrial power systems.
• Carry out transformer testing (winding resistance, oil BDV, ratio test) and switchgear/breaker testing (contact resistance, timing tests).
• Perform solar-specific tests: string/IV curve testing, module polarity checks, inverter commissioning support, performance ratio verification.
• Support SCADA/RTU functional testing, loop checking, and ELV systems commissioning (CCTV, WMS, UPS) as applicable.
• Prepare and maintain test reports, commissioning protocols, and punch/snag lists per ETPL's document control standards.
• Coordinate with site engineering, vendors, and client/TPI representatives during witness testing and energization.
• Support energization activities and compile post-commissioning handover documentation.
• Flag test discrepancies/non-conformances and coordinate corrective actions with the design team.
