We have developed a method to obtain the ratio error and phase displacement of a single-stage current transformer (CT) by measuring four parameters in a CT equivalent circuit. The method was applied to CTs under test with a primary current in the ran

Methods to measure the burdens of voltage transformers (VTs) and current transformers (CTs) in situ in instrument transformer test systems have been developed using non-reactive resistors connected in series with the VT secondary and in parallel with
