The reliability of any switchgear installation is fundamentally determined by the quality of its commissioning and the rigor of its first acceptance tests. These procedures, outlined in international standards, are non-negotiable for ensuring safety and performance. They include meticulous mechanical operation checks, measurement of contact resistance (which should be very low, e.g., ≤500 µΩ), insulation resistance tests, and high-potential (hipot) withstand tests at specified DC voltages for a sustained period (e.g., 15 minutes)-1. Skipping or shortening these tests invites future failure. Sinotech Group emphasizes quality at every stage. We recommend and can help coordinate factory acceptance tests (FAT) where clients can witness key performance verifications before shipment. Furthermore, we stress the importance of proper site commissioning performed by qualified personnel. Our technical experts can provide guidance on commissioning protocols and connect you with certified service partners in your region. Investing in proper commissioning is the final, critical step in securing your switchgear investment.
