Abstract
A method of operating an electrical machine is provided. The method includes the steps of providing a brushless excitation system including a diode rectifier having at least one diode, sensing heat energy generated by at least one resistor connected in parallel with the at least one diode, wirelessly transmitting a signal representative of the heat energy, detecting a deviation of generated heat energy from the at least one resistor, and generating a signal indicating an error if the deviation in generated heat energy exceeds a predetermined threshold.
