dcterms:description
This paper describes an innovative procedure for calibrating sets for evaluating instrument current transformer (ICT) errors. The innovation lies in the use of a current source for generating a measured current. There is an adjustable current source at 50 Hz mains frequency with a current transformer on its output. The internal impedance must be sufficiently high to eliminate the methodic error due to calibration. Calibration is carried out by means of a measuring system controlled by a PC through an IEEE 488 bus. Known values of the simulated ratio error and phase displacement are compared with the values measured by the device that is being tested. A software tool determines the simulated and measured error at each calibration point and determines whether the instrument that is being tested fulfils the parameters stated by the manufacturer.
