Product Description

Lightning Protection Company Electric Field Meter Warning Lightning Monitoring System


A. Introduction of atmospheric electric field meter system

Atmospheric electric field meter as the main instrument to detect the intensity of the electric field in the atmosphere, plays an important role in lightning monitoring and early warning, electric field meter is a high-tech highly integrated atmospheric detection equipment, divided into three parts: outdoor probe, instrument box and indoor data processing display center. The probe detects the change of atmospheric electric field, and the circuit in the instrument case converts the detection result to analog-to-digital, and packages it with time information, and transmits it to the indoor host computer remotely through RS-485 serial port or wireless GPRS. 


A lightning monitoring system is used to observe, collect and analyse lightning activities so that a preventive measure to protect power equipment from severe damage can be planned. An effective lightning monitoring system is crucial to ensure the reliability and sustainability of the electrical energy supply. Despite numerous published papers on this topic, there seem to be an absence of comprehensive review papers that evaluate monitoring technologies and their performances. Owing to the literature gap, this paper is written to summarise the working principles of the relevant sensors and the various methods of data transmission, storage and analysis, as well as the various ways of predicting the occurrence of lightning strikes. This knowledge will contribute to the development of a new online lightning detection system that will be more efficient, without reducing the effectiveness and sensitivity of the system, by utilizing the available technology for data transmission and analysis.



The system adopts a master-slave three-level network supervision structure. It can timely reflect the time of lightning strike, energy level, action of lightning protection facilities and dynamic changes of grounding system after lightning strike. The system can be widely used in electric power, petrochemical, computer, finance, construction and national defense and military fields to provide the most timely and accurate lightning strike data for managers.
The network system consists of three parts: a central management center at the top level, handheld mobile information collection equipment for secondary maintenance personnel and a wireless terminal for lightning status collection at the terminal.

Central management center: according to the working distance, decide to contact with the mobile collection equipment of the system monitoring sub-station through direct broadcast or GPRS network to obtain the status information of each monitoring point in real time.
Handheld mobile collection equipment: communicate with the wireless monitoring data collection terminal in a wireless way and transmit the collection results to the central management center. Wireless collection terminal. Work independently, collect and record automatically, and its data are read by the mobile devices of inspectors at any time or transmitted through optical fiber, or GPRS system can be used for transmission.
In addition, through the backup interface of the collection terminal, other relevant data collection channels can be added to realize the control of ground resistance changes, temperature, wind speed data, ice and snow thickness along the route. It can be upgraded according to the needs of the site. ◆HD-LDL lightning protection online monitoring management system basic functions
(1) wireless terminal installed in the monitoring point (terminal installed above the tower), through the sensor to achieve real-time collection and storage of lightning occurrence state and lightning arrester protection state information, can record time times 999 times cycle record, time accuracy of seconds, energy records are divided into four levels that is super, strong, medium, weak.
(2) inspection personnel carry special handheld mobile collection equipment, the site history records and temporary needs of the data for wireless reading, the farthest distance collected for 500 meters.
(3) The central management machine reads back the data of the handheld device. These data can be input to the management software system for analysis and statistics. Its software aims to obtain the monitored time of lightning occurrence, geographic distribution parameters and grounding status, and also realize the information management of the whole system, timely grasp of inspection personnel out of work time, work location, the formation of statistical reports of work content, and even provide memorial information for failure and safety accidents.
(4) The bottom wireless collection terminal collects the change trend of grounding resistance through the grounding resistance measuring probe regularly or directly in real time and stores it in the terminal. The lightning sensor collects information on the location, intensity, quantity and time of lightning occurrence. Its embedded software includes sensor data acquisition, data processing identification and communication protocol.
(5) Power supply: Solar independent power supply.
