- Abstract:
- This paper describes methods and criterions for errors determination of current transformers (CT). It is shown that there is need for technical standards modifications, because traditional governmental standards tests are based on purely sinusoidal conditions. Based on sampling and composite errors, which can be used for the errors determination in non-sinusoidal system, experimental results are presented, comparing two toroidal CT, one with nanocrystalline alloy core and another with FeSi core both submitted to sinusoidal regime.
