Using PF and PF testing techniques to guide electrical testing, maintenance, and asset replacement planning and ...

2. Telltale sign. Evidence of partial discharge activity is the white discoloration on the coil insulation surface of this stator winding of a 9,490-kVA, 600-rpm generator from the UK’s Brush ...

The heat generated in the stator winding has to be removed through the main ground wall insulation, and this is a significant factor in the machine’s electromagnetic and heat transfer design.

Impregnation of the stator windings with trickle varnish resin ... no major difference was observed after the PEEK slot and phase insulation material as well as the PEEK magnet wire was installed. The ...

tearing the insulation, copper and stator iron until the stator windings and core iron are gouged so deeply that the ring and rotor stop. During the gouging and tearing process, the rotor can ...

Check the belts, motor mount as well as the rotor and stator. Testing the motor windings ... In addition, you should also test the winding insulation to measure its resistance.
