In the paper the influence of conductive disturbances on transformation of fault current by inductive protective current transformers is described. Analysis of the results from laboratory studies show, that for such condition primary current up to which the current transformer will comply with the requirements for composite/ratio error is decreased. This is caused by increased magnetic flux density...
To assess the quality of electricity supply through the power networks it is necessary to use instrument transformers or other devices for measuring voltages and currents of considerable values. In many terminals the quality of electric energy is significantly deteriorated and this result in the occurrence of the conducted disturbances in the primary signal of the instrument transformer which cause...
