变压器铁芯接地电流在线监测与保护系统的研究与开发

摘要

This paper introduces a real-time and on-line monitoring (and protecting) system for the trans-former core grounding current. The system is developed on the basis of further research on transformer core multi-point grounding fault. It implements signal collection, measuring, real-time displaying, data transmission, computing, analyzing, storing, protecting and so on. The application of this system will improve the reliability of the transformer.%本文介绍了一种实时在线监测变压器铁芯接地电流的监测（与保护）系统。该系统是在变压器铁芯多点接地故障深入研究基础上开发的，实现了信号采集、测量、实时显示、数据传输、计算、分析、存储和过电流限流等功能。该系统的应用提高了变压器运行的可靠性。
