Remote monitoring of high-voltage disconnect switches in electrical distribution substations

An autonomous, wireless multi-variable smart sensor is presented able to gather, validate, and locally process data on both position alignment and temperature in remotely-operated high-voltage disconnect switches, as part of an instrumentation system which, integrating small, smart, and deeply embedded “field” devices in large numbers, may address the data requirements placed by new sophisticated asset management criteria applied to primary distribution substations in smart electrical grids.
