Commissioning

Structured Approach

365 Transformer Services provides comprehensive transformer commissioning and energization services to ensure newly installed, repaired, or relocated transformers are placed into service safely and reliably. Our commissioning process verifies electrical integrity, mechanical readiness, and operational compliance prior to initial energization.

All commissioning activities are performed in accordance with IEEE, NETA, OSHA, utility requirements, and transformer manufacturer guidelines. Our structured approach reduces risk, prevents premature failures, and supports a smooth transition to normal operation.
