We provide expert commissioning services for high voltage switchgear, verifying that all components meet operational and safety standards before being integrated into your network. Our team meticulously inspects, tests, and calibrates switchgear to ensure reliable performance under high-stress conditions. With our thorough commissioning process, we help prevent failures, reduce downtime, and extend the lifespan of your equipment, ensuring your power distribution system operates at peak efficiency from day one.
Visual Inspection: Check for physical damage, proper installation, and cleanliness.
Mechanical Operation: Verify the mechanical operation of the switchgear components, including switches, circuit breakers, and disconnectors.
Nameplate Verification: Confirm that the equipment matches the specifications and nameplate details.
Wiring Check: Ensure all control and power wiring connections are correct and secure.
Phase-to-Phase and Phase-to-Ground Testing: Measure the insulation resistance of each phase to ensure there are no insulation breakdowns.
Busbar Insulation Testing: Check the insulation resistance of busbars.
High-Pot Test (Dielectric Withstand Test): Apply a high voltage to the switchgear to ensure it can withstand operating voltages.
Partial Discharge Testing: Detect any partial discharges within the insulation to identify potential weak spots.
Measure the resistance of circuit breaker and disconnect switch contacts to ensure they are within acceptable limits.
Manual Operation: Verify the manual operation of switches, circuit breakers, and disconnectors.
Electrical Operation: Test the electrical operation of all devices, including remote control functions.
Interlock Testing: Ensure all mechanical and electrical interlocks operate correctly to prevent unsafe conditions.
Relay Testing: Test the protection relays for correct operation and settings.
CT and VT Testing: Verify the correct functioning of current transformers (CTs) and voltage transformers (VTs).
Circuit Breaker Timing Test: Measure the opening and closing times of circuit breakers.
Check the integrity and continuity of the grounding system. Measure the earth resistance to ensure it is within acceptable limits.
DC Supply Verification: Ensure the DC supply for control and protection systems is reliable.
Heater and Ventilation System Check: Verify the operation of heaters and ventilation systems to prevent condensation.
System Integration Tests: Conduct tests to ensure the switchgear integrates properly with the overall electrical system.
SCADA and Communication Testing: Verify the communication between switchgear and the supervisory control and data acquisition (SCADA) system.
Prepare Test Reports: Document all test results and observations.
Update Drawings and Schematics: Ensure all as-built drawings and schematics are updated.
Handover to Operations: Provide a comprehensive handover to the operations team, including training and documentation.
