Abstract

The paper describes an intercomparison of measuring systems for current transformers accuracy testing between three laboratories Koncar - Instrument Transformers, Koncar - Electrical Engineering Institute and Electrical Engineering Institute Nikola Tesla. All laboratories are accredited according to EN/ IEC 17025: 2017 standard. The obtained discrepancies in ratio and phase errors are within participant’s declared measurement uncertainties. All laboratories have confirmed their competence (|En|≤1) for the applied measurement methods, in accordance with EN ISO/ IEC 17043.
