Abstract
In order to increase the integrity of existing generation systems, it is essential to discover
problems well in advance. An investigation into methods for diagnosing multiple incipient
faults on a 2-pole synchronous generator is presented. Simulation of the generator on a
finite element analysis (FEA) software package is used to predict the effects of these
faults. Experimental analysis of the generator under fault conditions is then conducted
and confirms the predicted behaviour. The investigation utilises search coils and shaft
brushes as condition monitoring tools. Results of the investigation indicate definitive
relationships between the faults and specific harmonics of the output signals from the
condition monitoring tools. The presented techniques are viable and future work can
utilise these results in the design of a fault diagnosis system.
