Erection, Testing & Commissioning

We provide end-to-end Erection, Testing & Commissioning (ETC) services for electrical systems and substations up to 400kV. Our expert team ensures all equipment is installed as per engineering drawings, tested to international standards, and commissioned safely and efficiently to meet project timelines.

Erection Testing and Commissioning
  • Mechanical erection of transformers, switchgear, and panels
  • Cable laying, glanding, and termination
  • Relay testing and calibration (primary & secondary injection)
  • Transformer ratio, winding resistance & vector group testing
  • CT/PT testing, polarity, and burden verification
  • Functional and interlock testing of protection schemes
  • Breaker timing test and contact resistance measurement
  • Pre-commissioning checks for HT/LT systems
  • Cold and hot commissioning of substations
  • System energization with client and utility coordination

Why Erection & Commissioning Matters

Proper erection and commissioning ensure that the electrical system performs safely and optimally from day one. It helps detect errors early, ensures compliance with standards, and lays a strong foundation for long-term performance and reliability.

  • Ensures installation quality
  • Validates system integrity
  • Reduces future failures
  • Improves safety and reliability
  • Ensures operational readiness
  • Minimizes project handover delays

Scope of ETC Services

Our services cover power distribution and transmission projects for industries, utilities, EPC contractors, and infrastructure. From installation to energization, we adhere to IS, IEC, and IEEE standards using certified test equipment and documented protocols.

We provide detailed test reports, system configurations, as-built drawings, and operation manuals post-commissioning. Our engineers are trained for GIS, AIS, and hybrid substation systems.
