Detection of Short-Circuited Turns in Secondary Windings of Current Transformers Using Method of Digital Current and Voltage Oscillography While Reading Volt-Ampere Characteristics

Abstract

The paper contains processing results of digital current and voltage oscillograms as effective, mean and peak volt-ampere characteristics of a serviceable current transformer with short- circuited turns. Digital current and voltage oscillograms and curves of volt-ampere characteristics permit to detect presence or absence of short-circuited turns in secondary windings of current transformers.
