The method for detecting fault types and the fault current waves in transmission systems was proposed. This paper describes the investigated results regarding the accuracy for parameter fitting in the proposed method. The errors included in the measured current and the current distortion are the main factors deciding the parameter fitting accuracy. Required current errors are evaluated by parameter detection using estimated error rate curves of current transformers. The influence of harmonic waves and switching surge on the current wave estimation is also studied.
