Abstract

Method and system for determining degradation in a respective grid of power resistors (38) in a propulsion subsystem (24) are provided. The system includes a signal monitor (52) configured to monitor respective signals indicative of an estimated grid resistance value based on a first set of operational and/or environmental conditions. A first module (54) is coupled to receive the value of the estimated grid resistance for adjusting the received grid resistance value relative to a nominal grid resistance value based on a second set of operational and/or environmental conditions to generate an adjusted grid resistance value. A second module (58) is coupled to receive the adjusted grid resistance value for comparing that value against the nominal grid resistance value so as to determine the performance of the respective resistor grid.
