Abstract

In the field of electrical power systems there is provided a method of supervising the operation of a plurality of current transformers that are arranged in respective current transformer groups (24, 26, 28, 30, 32, 34, 36; 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108) within differing protection zones (14, 16, 18; 74, 76, 78) of a multi-phase electrical power system (12; 72). The method of supervising comprises the steps of: (a) identifying a faulty protection zone (14, 16, 18; 74, 76, 78) within the electrical power system (12; 72); (b) identifying a faulty current transformer group (24, 26, 28, 30, 32, 34, 36; 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108) within the faulty protection zone (14, 16, 18; 74, 76, 78); and (c) identifying one or more faulty phases (A, B, C) within the faulty current transformer group (24, 26, 28, 30, 32, 34, 36; 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108) within the faulty protection zone (14, 16, 18; 74, 76, 78).
