The rewind team were excellent in executing their duties, we lost time at the beginning of the project and they recovered significant amount of that time with no serious safety incident
High oil contamination created excess looseness, movement and friction on the bars, which resulted in a gas into water leak on a bottom bar. It was decided to rewind the original hollow conductor cooling bars with stainless steel stator bars.
The use of the rewind kit available at the plant was an important factor for the quick recovery of the unit and illustrates the importance of having a full spare kit available.
