Shorted turns tester
Splet10. apr. 2024 · The pole drop test is the most widely applied means of detecting shorted turns in the rotor field winding of salient pole wound field synchronous machines … SpletShorted turns in generator cylindrical rotor field windings can contribute to vibration problems due to rotor thermal bending from the uneven heating associated with non-symmetrical dc current flow and watt losses in faulted windings. Shorted turns can also cause unbalanced magnetic flux in the air gap that can also aggravate vibration problems.
