METHOD AND APPARATUS FOR DETECTING FAILURE IN BRUSHLESS EXCITER FOR POWER GENERATOR

摘要

PROBLEM TO BE SOLVED: To aim at a system which detects diode failure and other failure surely in a brushless excitation system.;SOLUTION: The method includes: preparation of a brushless excitation system 10, which includes a diode rectifier 30 having at least one diode 32; sensing 42 of thermal energy generated by at least one diode; detection 20 of deflection of the thermal energy generated from at least one diode; and generation 20 of a signal for indicating a diode failure or defect when the deflection of the generated thermal energy exceeds a predetermined threshold deflection level.;COPYRIGHT: (C)2010,JPO&INPIT
