Case study

Transformer: 2.2KW three phase auto transformer Lead time: 7 days Three phase transformer rewindOur customer had a critical breakdown on a 2.2KW auto transformer which powered a major piece of plant machinery. Our engineers carried out a full inspection which resulted in the transformer requiring a full rewind. Our transformer team stripped, rewound all three phases, rebuilt and had the transformer back onsite within 7 days. This ensured the minimum amount of downtime for our customer. Before starting the repair, our technical team offered the customer a written report on the critical failure of the transformer. Once the repair was complete, the customer was issued with working drawings and test certificates as required.
