Guidance on high-speed testing of turbo generator rotors
Engineers responsible for generator maintenance are often posed with the difficult question of whether to send the rotor off-site for high-speed balancing and testing or not. It is generally considered that by doing so is the lower risk option, however there can be substantial operational and financial pressures against doing so. This guide aims to provide operators with information required to help them make informed decisions as to whether to carry out high speed testing of generator rotors following repair or maintenance. The practice varies substantially across the world and engineers can be presented with difficult decisions to make under financial pressure.
