Development of Shorted-Turn Sensor for Generator Rotor Windings

As a fundamental investigation to develop a sensor which is able to detect shorted turn phenomenon of generator rotor, we have experimented with self-made sensor using flux generator and high-resolution oscilloscope. We have recorded sensor-induced voltage according to the different condition, such as variations of turn, diameter and length of sensor. Based on the acquired data, we analyzed and simulated under similar circumstances of actual spot to maximize reliability. We have a plan to invest more resources to supply power plants with the developed sensor for ourselves.
