Pre-Commissioning & Testing Services for LT & HT Panels

Reliable Panels Start with Precise Testing

At 3 Phase Power Solution, we provide specialized Pre-Commissioning and Testing Services for LT & HT Panels, ensuring that your electrical distribution systems are fully compliant, safe, and performance-ready before energization. Our expert team follows industry-best practices to verify every connection, protection device, and control logic — giving you complete confidence in your infrastructure.

Scope of Services

⚡ Visual Inspection & Compliance Checks
We start with a thorough visual examination of the panel construction, wiring layout, busbar system, and compliance with design drawings and standards.

🧪 Insulation Resistance Testing (IR)
Critical for both LT and HT panels, we conduct insulation testing using calibrated instruments to ensure safe and secure cable installations.

🔍 High Voltage (HV) Testing / Dielectric Testing
To verify insulation strength, especially in HT panels, we perform HV testing as per IS/IEC standards.

🔁 Relay & Protection Scheme Testing
Testing and verification of protective relays, trip circuits, interlocks, and breaker coordination to ensure timely fault isolation.

🔄 Functional & Interlock Testing
We validate the operation of ACBs, VCBs, MCCBs, isolators, interlocking systems, and automatic/manual transfer logic.

📉 Current Injection & CT/VT Ratio Testing
Ensuring accurate metering and relay protection through primary and secondary injection tests of CTs, VTs, and protection relays.

📃 Test Documentation & Certification
A complete dossier of all test results, certifications, and recommendations is submitted for your project records and regulatory compliance.
