The following paper focuses on generator end winding vibrations. Monitoring systems have been developed for measuring them however sensible methods for analysis have not been found yet. A reduced end winding model and modal analysis of it are further described. The resulting analytical modal representation of vibration is used to evaluate a method for interpolation the spatial end winding vibration...
The development of cost-effective maintenance strategies requires diagnostic tools which detect any defects as early as possible to enable the determination and selective planning of the requisite repair measures. The sensitive partial discharge (PD) measurement method enables the detection of individual weak points developing in generator high voltage stator insulation in their initial stages. However,...
