Use of Discharge Resistor to Improve Transient De-Excitation in Brushless Synchronous Machines

The discharge resistor is only used in case of electrical trip to reduce the field current as fast as possible and to minimize the damages produced by the short-circuit current supplied by the synchronous machine. The connection of the discharge resistor is done by opening the field breaker and it i...
