A flux probe test determines the existence of rotor winding shorted turns by measuring the magnetic flux produced by each coil in a generator's rotor.

Shorted-turns are the result of failed insulation between individual windings in generator rotors. The impact of operating with shorted turns can result in abnormal vibration, load limits, higher operating temperatures and forced outages.

Generatortech's Acquisition and Analysis Program has been designed to quickly and easily acquire and save data from flux probes.

The success of the detection system requires separating the slot leakage flux data from the distortion factors.

Shorted-turns are the result of failed insulation between individual windings in generator rotors. The impact of operating with shorted turns can result in abnormal vibration, load limits, higher operating temperatures and forced outages.

Shorted-turns in the field winding can cause operating conditions which may limit unit loads. If conditions are extreme, forced outages may occur.

Generatortech Rotor Winding Shorted Turn Flux Probe testing is the most comprehensive testing performed while your generator is online and at-speed.

Generatortech estimates 50% of the rotors in operation may have one or more shorted turns. Periodically monitoring for shorted turns will help establish whether new turn shorts are developing and when corrective action should be taken.
