The Design of Electronic Current Collector Based on Fault Travelling Wave Location

This paper presents a new-type design of electronic current collector based on fault travelling wave location. It increases high-speed signal acquisition circuit to collect fault travelling wave signal. While in order to transmit the data of failure travelling wave to merging unit (MU) for secondary equipment to make a fault distance analysis, it proposes a new communication protocol between the collector of current transformer and MU in this paper. Furthermore, the design has been proved that the new electronic current collector can not only realize the basic acquisition of measurement and protection data, but also can realize the complete acquisition of fault travelling wave signal and achieve effective communication.
