Learn about HV transformer testing and commissioning. Discover key steps like insulation, ratio, and resistance testing for safe, efficient operation.
HV Transformer Tests and Commissioning
High Voltage (HV) transformer testing and commissioning is a critical step to ensure safe and reliable operation of power transmission systems.
These procedures validate the transformer's mechanical and electrical readiness before it goes into live operation.

HV Transformer Testing Process
Testing is performed on-site after delivery and installation. Key tests include insulation resistance, winding resistance, turns ratio, oil analysis, vacuum testing, and dielectric strength tests.
Each test aims to detect potential faults such as insulation failure, internal short circuits, or incorrect wiring.

Commissioning Steps
After all tests are successfully completed, the transformer is integrated into the system and energized.
Steps include energization, load monitoring, infrared thermal inspection, and SCADA system integration.

Critical Safety Considerations
Due to the high voltages and currents involved, only certified professionals should perform these tests and commissioning operations.
All testing equipment must be calibrated, and procedures should follow national and international standards.
