Monitoring of the service condition of large rotating apparatus. Turbine-generators and motors.

In corporation with SK-energy and ELTEK, it is the intention to develop and test different methods for assessing the service condition of the insulation system in large rotating apparatus based on the on-line monitoring of the PD-signals in the apparatus. The fundamental evaluation is based on investigation performed on machines in a test laboratory environment and on model systems. This, in order to evaluate the validity of an on-line test on a turbine generator and motor in a power station.
