Abstract :
This paper describes a relation for resulting error by measurement of electric power or energy at high voltage networks using instrument transformers. A dependence of instrument transformer errors on their parameters, measured current or voltage and burden is theoretically derived. Theoretical results are completed with results of measurement on transformers for 22 kV network.
