Optical power generator system condition status indicator and methods of indicating same

Abstract

An apparatus and method to monitor temperature variation in electrical system generator components is provided. A temperature probe comprising temperature information conveyor that directly transfers temperature variation information to a temperature-sensitive light window is utilized. A pair of light guides can be employed, wherein the first conveys light to the light window from a light source, and light passing from the window is captured by the second light guide and conveyed to a light sensor. Within pre-selected temperature ranges light passes through the window, but pre-specified temperature variations will close the window thereby blocking the light so as to signal a critical temperature variation has occurred. The temperature information conveyor is chosen so as to have definite properties in terms of a heat conductivity coefficient to promote rapid, direct conveyance of temperature variation information. It further can be formed to enhance the speed and efficiency of temperature information conveyance. The apparatus and methods permit any selected component or portion of an electrical generator system to be monitored. Moreover, multiple components can be monitored simultaneously.
