How to measure ac currents in a bundle of inaccessible, enclosed conductors has been a challenging problem but with many potential applications. This paper presents a method to solve the problem using an array of magnetic field sensors. The proposed method consists of two novel ideas. The first idea is to use an off-site calibration method to establish sensor parameters including sensing position...
Current transformers (CTs) are an indispensable equipment for power system current measurement. If a fault occurs in a power system, iron cores of CTs may face saturation problem and cause current measurement errors, resulting in false responses in protection relays. This research proposed a new current measurement technology using Hall integrated circuits (Hall ICs) symmetrically surrounding a power...
