Abstract
A status detection apparatus for electrical equipment includes a plurality of distributed multiparameter sensors in a containment vessel or other fluid filled region of the electrical equipment. The sensors are capable of providing data relating to plural parameters of the fluid simultaneously at different positions in the fluid. The data provided by the sensors can be processed to permit localization of incipient faults or can indicate other operating states when combined with known flow data of the fluid through the electrical equipment. A method for detecting status of electrical equipment includes sensing parameters simultaneously at multiple locations in the fluid and determining operating status based on the sensed parameters.
