The significance of the lightning arrester online monitoring system is to monitor the full current and lightning strike frequency of the lightning arrester in real time. By analyzing and fitting the monitored data, and combining it with the on-site working conditions, it can timely detect problems such as ceramic bushing leakage current or insulation rod leakage current increase caused by pollution or internal moisture of the lightning arrester, in order to avoid accidents.

It mainly consists of two parts:

1. MOA current monitor is mainly used for real-time and online monitoring of the full current and lightning strike frequency of lightning arresters.

2. Intelligent online monitoring IEDs are used for on-site data collection and recording, collecting real-time data from various MOA current monitors on site, and communicating data with the backend through RS485.

Function Introduction:

Adopting a current sampling method with no residual voltage and full isolation to achieve high-precision measurement

Adopting digital filtering algorithm to eliminate the "zero drift problem" caused by analog filters

Adopting advanced compensation technology, it has good universality and interchangeable measurement

Adopting a distributed measurement structure, namely on-site measurement and digital transmission

Can be installed with electricity, which means there is no need for the main equipment to be powered off for installation, making it convenient and fast to connect to the system
