摘要
: An improved rotor for detecting earth fault of rotor winding through DC rings of brushless exciter in synchronous machines, comprising DC rings (5), rectifier wheel (4), non-continuous contact type brush gear (10), Characterized in that DC rings are mounted on one side of the rectifier wheel (4) and modified to function as slip rings provided with access for non-continuous contact type brush on brush gear device (10) wherein the said brush gear device is actuated at intervals to collect ground fault signals. No. of Pages : 14 No. of Claims : 5[IN-KOL-2008-01098A]
