Importance of Two Algorithms Use in Detection of Shorted Turns on Salient Pole Machines Company: Canadian Utility Machine Description: Hydrogenerator, 13.8 kV, 47 MW, 74 pole Importance of Two Algorithms Use in Detection of Shorted Turns on Salient Pole Machines: Flux monitoring via permanently installed air gap flux probes is a proven technology used for many years in synchronous machines to determine presence of turn-to-turn shorts in a rotor winding. This information is critical in planning maintenance and vibration analysis. Originally used only on high speed round rotor turbo-generators, this technology is now used on hydro-generators and motors as well. Due to larger rotor diameters and possibility that rotor shape is not completely round, the voltage induced in flux probe will be af
