Abstract
The present invention provides a method for determining voltage loss in an electrical device. The method includes the steps of obtaining an array A of voltage values corresponding to at least one current interrupt measurement at current I, wherein Icorresponds to current values I, I, . . . , I, wherein subscript n is at least 3; forming an array D of difference values using a difference of the array A over an elapsed time; processing the difference values of the array D to obtain V; determining Vfor each Ito form an array V of V; and calculating a resistance, R, using the array V, thereby determining voltage loss in the electrical device.
