Pre-Commissioning Testing

Pre-Commissioning Testing is a critical step in ensuring that all electrical systems and equipment are installed correctly, function as intended, and are ready for safe commissioning. This phase involves detailed inspections, functional testing, and verification to detect any issues before energizing the system.

Insulation resistance testing for cables, motors, and transformers
Continuity and polarity checks
Loop checking of control circuits
Primary and secondary injection testing of protection relays
Functional testing of switchgear, breakers, and control panels
Verification of grounding systems and earthing continuity
Voltage withstand (HiPot) testing for high-voltage equipment
Transformer ratio, vector group, and winding resistance testing
Testing of CTs and PTs for accuracy and polarity
Relay logic and interlock verification

Importance of Pre-Commissioning

Pre-Commissioning minimizes the risk of equipment failure, enhances system reliability, and ensures all components meet operational and safety requirements before the final commissioning phase. It helps identify and correct errors early, saving time and cost during the actual commissioning and operation.

Ensures safety and regulatory compliance
Reduces operational risks
Validates system performance
Ensures installation quality
Prevents startup failures
Supports a smooth commissioning process

Scope of Testing Services

Our Pre-Commissioning Testing covers a comprehensive range of services including HV & LV system testing, panel verification, instrument calibration, relay logic checks, and cable terminations. Each test is carried out by qualified engineers using calibrated and certified equipment to ensure accuracy and reliability.

We provide detailed test reports, certifications, and assistance in compliance with international standards like IEC, IEEE, and IS. Our testing service is tailored for substations, industrial plants, infrastructure projects, and utility networks.
