Testing & Commissioning

Testing & Commissioning is a critical phase that ensures every electrical installation—whether EHV, MV, or LV—operates safely, efficiently, and in full compliance with international standards before being handed over for live operation. Our process begins with meticulous pre-commissioning inspections, where engineers verify cable laying quality, joint and termination accuracy, gland tightening, equipment alignment, earthing continuity, and mechanical integrity of panels and switchgear.

This is followed by a comprehensive series of electrical tests conducted using state-of-the-art calibrated instruments. These tests include insulation resistance measurement to evaluate dielectric health, high-voltage withstand tests (Hi-Pot) to confirm cable insulation endurance, VLF testing for XLPE power cables to detect early-stage degradation, Tan-Delta measurements to identify insulation ageing, and partial discharge analysis to locate potential weak points and voids in the system.

Additional tests such as phase sequence verification, contact resistance measurement, continuity checks, relay logic verification, and protection scheme validation ensure that every electrical component responds accurately to faults and switching conditions.

Once all test results meet the required IEC/IS/OEM standards, the system proceeds to functional testing, where control circuits, interlocking signals, tripping mechanisms, motor operations, transformer functionality, RMU/VCB operations, and SCADA/automation communication are thoroughly validated.

Energization is carried out through a controlled and safety-driven procedure, where voltage levels, load conditions, heating cycles, system stability, and protection relay responses are continuously monitored. Our engineers document every test value, observation, and parameter reading to maintain full transparency and traceability.

After successful commissioning, we provide the client with a complete handover package, including detailed test reports, calibration certificates, as-built drawings, safety compliance documents, and operational guidance for on-site staff. This end-to-end approach ensures that the electrical system is not only technically sound but also optimized for long-term, trouble-free operation.
