Operation Status monitoring System for Lightning Arrester on Line

Lightning is a kind of natural discharge phenomenon in the atmosphere. But lightning strikes are a kind of meteorological disasters which threatens seriously for people's life and property. Lightning protection device is designed to eliminate or mitigate such disasters. Such device with limited service life and strike times must be monitored by some security detection system for their maintenance and components or parts replacement. One security detection monitor system for monitoring lightning arrester operation status is designed and it is consisted of center management computer system and a quantity of terminal lightning arrester monitor. The center management computer system gives commands and receives data for each terminal lightning arrester monitor which sampling and collecting the data of monitored lightning arrester operation status, then analyze the received data and alarm and display diagnose results for manager. So the operation status of each lightning arrester can be understood and some maintaining program can be done. Some experiments have been done and the system operation is accuracy, stable and reliable.
