OPERATION & MAINTENANCE OF POWER PLANTS
WHAT CAN ENSURE MY PLANT‘S LONG-TERM EFFICIENCY?
Monitoring vibration and bearing temperatures are important preventative maintenance techniques
plant to plan for a complete rewind at a later date and improve the reliability of the motor until that time arrived.
EXTENDING SERVICE LIFE Sulzer suggested reconfiguring the windings by breaking the star point and connecting the original supply leads to create a new star point. Tis will extend the service life of the stator winding by taking the in-rush current away from the phase coils, reducing the stress on the windings and allows the operator to start planning for a complete rewind in the future. Having reinsulated and varnished the new windings, the motor was reassembled with new bearings and seals before the remainder of the testing was completed. Both motors were shipped to the power station and reinstalled by Sulzer’s field technicians before being commissioned. Adrian Larmour at Sulzer comments: “Our
framework agreement with this customer was a great advantage because all the terms and conditions have already been agreed. Tis saved time when repairs were needed and also provided assurances of the quality and the procedures used to complete the project.”
EXPERTISE AND EFFICIENCY As with any work that Sulzer carries out, customers are invited to visit the service centres to review progress or see first-hand any unforeseen developments that are uncovered during an inspection. Trough continuous communication and a transparent repair process, customers receive an efficient and cost-effective solution. Larmour concludes: “Te final result from this
project has been very positive. Downtime has been minimised and plans are in place to make further improvements during the next planned outage.”
