Compact electric field change meter and its application in lightning detection and fault analysis for power grids

A compact electric field change meter combined the fast and slow electric field change measurement was developed. This paper presented the structure, the features and the calibration method of the instrument as well as the collected typical lightning discharges, including the return stroke and preliminary breakdown pulse train of cloud-to-ground lightning, the compact intracloud discharge, the conventional intracloud discharge and the continuing current. The application of the instrument for fault analysis of transmission lines, especially those caused by lightning return stroke and continuing current, and other non-contact measurement of transients were discussed and expected.
