Optical Fiber Communication Technology in the Capacitive Devices and Arrester Monitoring

Abstract

This paper introduced a new distributed capacitive devices and arrester on-line monitoring system. Monitoring system for traditional voltage zero crossing synchronization method susceptible to harmonic interference, electromagnetic interference cannot be sustained stability monitoring, A synchronous manner through a distributed data acquisition and fiber-optic communication believed to be monitoring equipment leakage current and voltage signals, And by the integrated processing unit, In order to improve the reliability of monitoring data. Comparison test and field operation results show that measurement accuracy and stability of the monitoring system has greatly improved than traditional monitoring methods, practical and promotional value.
