Medium-Voltage Instrument Transformers Calibration up to 150 kHz: Methods, Reference Systems, and Comparison of Performance
This article presents a European interlaboratory comparison of measurement systems and calibration procedures for the wideband characterization of instrument transformers (ITs) for medium voltage (MV) grids up to 150 kHz. The work, developed within the European Partnership on Metrology project 22NRM06 ADMIT, describes...
