MEASUREMENT-TRANSFORMER ERROR CAUSED BY NON-SYMETRY OF MASURED CURRENT

Peter Jahn

   In the paper, the error caused by non-symmetry of the current in instrument transformers with a ferromagnetic core is described and discussed briefly. An example, including the analytic solution, is given for the case of unbalanced triangular current waveforms containing the even-numbered harmonics.

Keywords: instrument transformers, measuring errors, magnetic core transformer.
