Rewinding of generator for ExxonMobil

Customer: ExxonMobil Exploration and Production Norway AS
Date: 30.05.2012

Exxonmobil contacted Karsten Moholt regarding a generator from Balder that had broken down and needed rewinding of the stator.

The stator was rewound and high voltage insulation tests were performed before and after the rewinding. The generator was painted and the air cooling system was overhauled and tested. In addition it was discovered that some of the bolts in the rotor anchor were broken. All of the bolts in the rotor anchor were replaced. The generator was inspected electrically and mechanically, and a no-load test run was performed before it was returned to the customer.
