Method for determining the operating status of a mv switching device of the electromagnetic type
Abstract:
A method for determining the operating status of a MV switching device is provided. The method includes providing a test signal to said test coil for an observation period of time. Measuring data is obtained which is indicative of the voltage at the terminals of the test coil and of the current circulating along the test coil during the observation period of time. Observation data is calculated which is indicative of the electric behavior of the test coil at the end of said observation period of time. A transformation function is selected which is indicative of the electromagnetic behavior of the electromagnetic actuator. First estimation data is calculated which is indicative of the operating status of the electromagnetic actuator.
