The basic requirements to metrological performance of high-voltage electromagnetic current sensors of electronic current transformers (ECT) has been defined. Sensors complying with these requirements provide ECT with the measuring information of required accuracy, are electromagnetically compatible with inputs of its electronic part and have information interoperability with it. References 6, figures 4, tables 7.
Key words: electronic current transformer, sensor, metrological performance.
