Repairs boost Kelvin’s generating capacity

Over the past 18 months Marthinusen & Coutts and ACTOM Turbo Machines have performed a comprehensive range of repairs and re- furbishments for Kelvin Power Station in Kempton Park. Marthinusen &Coutts recently completed a complex repair of one of the station’s 60 MW synchronous alternators, while ACTOMTurbo Machines per- formed general overhauls (GO’s) on five 60 MW turbine generator sets.This work by the two business units – ACTOMTurbo Machines (formerly Cetus Turbo Machinery which was acquired by ACTOM

The stator of the 60 MW synchronous alter- nator was damaged when the unit suffered a breakdown in March last year. Tests conducted on site by Marthinusen & Coutts established that three stator bars had been damaged, whereupon it was decided to replace a total of six stator bars. “Due to the fact that the winding is of a special single-layer type in which the strands in each sta- tor bar are individually brazed onto the associated strands of the bar next to it, the replacement of the stator bars was a prolonged process lasting several months,” said Rob Melaia, Marthinusen & Coutts’ engineering and technical executive.
