Remote type lightning arrester monitor

Remote type lightning arrester monitor (JC-OM200/JSH3)

1、 System Overview

Lightning is a discharge phenomenon that exists in natural meteorology, and the current and voltage contained in its discharge process are very high, which is very dangerous. In daily life, people will use lightning arresters to guide and eliminate safety hazards. However, during the use of lightning arresters, they may lose their intended function at any time due to equipment wear and aging. When they encounter lightning again, the people or things they originally protected will be greatly threatened. The integration of the lightning arrester online monitoring remote transmission system can provide real-time monitoring of the operation of the lightning arrester, thereby ensuring the safety of people's lives and property.

2、 Function Introduction

JC-OM200/JSH3 remote transmission lightning arrester monitor uses digital filtering technology and analog filtering technology in the fundamental wave method to filter out the fundamental component of the resistive current from the collected total leakage current at the end of the lightning arrester, analyze it to determine the operating status of the lightning arrester, and use wireless network to remotely transmit it to the monitoring center for monitoring personnel to call and view; When the detected data exceeds the preset value, the system will immediately issue an alarm message, prompting the staff to pay attention to the alarm area and quickly take rescue measures.

3、 Job characteristics
