✅ Insulating oil withstand voltage test (56kV)

✅ Winding resistance imbalance <0.5%

✅ Grounding system re-verification

On-site coordination

Training local electricians on HV switchgear operation

Coordinating utility company for switching impulse tests

Real-time temperature monitoring during initial loading

Progress Achievements

1.Installation adaptability

Split installation using available cranes (max unit: 8.5 tons)
