Traceability of Loss Measurements of Extra High Voltage Three-Phase Shunt Reactors

An overview of traceability issues of loss measurements of extra high voltage three-phase shunt reactors is presented. Loss measurements of a 345-kV-55-MVAr three-phase shunt reactor at Royal SMIT Transformers, including their uncertainties, are presented and discussed. The measurement results are confirmed with those obtained using a special high-voltage inductance bridge.
