Abstract

Current traveling waves are utilized to localize faults on transmission lines using conventional current transformers. This paper investigates high frequency characterization of the current transformer. The current transformer parameters at high frequencies are experimentally determined. They are obtained using frequency response measurements where the current transformer transfer function is calculated from measured impulse signals. Therefore its performance under transient conditions can be studied using different programs such as EMTP and MATLAB. The current transformer modeling and its experimental verifications show that there are good replicas of high frequency traveling waves over a suitable range for fault locators. The test results insure the CT applicability to traveling wave fault location.
