What is Recurrent Surge Oscillograph (RSO) Test?
by

1 Answer

Answer :

RSO test is performed to detect faults in rotor windings. The electrical faults in generator rotors fall into two main categories. The faults from the winding to the body and the faults between the parts of the winding (inter-turn faults). The existence of the faults will frequently display excessive mechanical vibration and cause serious concern.
