==Original Abstract Submitted==

A method for detecting an insulation fault in an unearthed electrical system, the system comprising a first rail and a second rail, each rail having an insulation resistance. The method comprises, in an initial stage: connecting the first rail to a relative ground through a first resistive component, wherein the first rail has an initial stage first rail voltage in the initial stage; and charging a capacitor to a capacitor voltage using the first rail, wherein the capacitor voltage is indicative of the initial stage first rail voltage. In a subsequent stage: connecting the second rail to the relative ground through a second resistive component; wherein the first rail has a subsequent stage first rail voltage; and determining if a fault has occurred by using the capacitor voltage and the subsequent stage first rail voltage.
