Abstract: 

IN ORDER TO RECOGNIZE THE RESPONSE OF THE RTD TO THE PARTIAL DISCHARGES IN HV ELECTRICAL MACHINES, SOME TESTS ARE CARRIED OUT ON A LABORATORY MODEL AND ON A HV GENERATOR. THE SIMULATED SIGNALS ARE INJECTED AT THE GENERATOR-TERMINAL-BOX AND THE RESPONSE OF THE RTD ARE DETECTED AND EVALUATED IN TIME AND FREQUENCY DOMAIN. THE RESULTS SHOW THAT MORE THAN 80% OF THE SIGNAL ARE DAMPED DURING TRANSMISSION ALONG THE GENERATOR WINDING AND THE RTD CAN BE USED TO DETECT THE PD SIGNALS THAT ARE INJECTED IN THE SAME SLOT. REFLECTED SIGNALS IN THE SLOT-ENDS AND RECEIVING NOISES THROUGH RTD WIRES SHOULD BE ELIMINATED USING DESIRABLE SIGNAL PROCESSING SYSTEM.
