Abstract :
Basic studies of the nature and method of detecting slot discharge phenomena in high-voltage stator windings show that the discharge is a result of loss of electric contact between conducting coil surfaces in the slot and the core. Several methods were studied for detecting and locating such discharges and the development of a slot discharge analyzer is described.
