Transformer Testing

Functional and stress testing is performed on every remanufactured transformer. We design your transformers in accordance with the latest revision of IEEE Std C57.12.00™ and all tests are performed in accordance with IEEE Std C57.12.90™.

Your remanufactured transformer is thoroughly tested for quality assurance as well as specification and performance confirmation. This ensures the transformer is service ready when delivered back to you. We provide full IEEE Class II tests.
