Product Overview:The lightning arrester in traction substations usually adopts metal oxide surge arrester (MOV). MOV is a nonlinear resistor made of metal oxide materials, which has the advantages of fast response time, large current capacity, low residual voltage, and no
1. The main functions of the lightning arrester intelligent monitoring meter are:
Automatic monitoring function
Periodic automatic monitoring of the full current, number of actions, and action time of the lightning arrester.
Data storage function
It has the function of saving and exporting historical data, and can automatically store 10000 monitoring data periodically.
communication function
Equipped with RS485 data upload function, meeting the MODBUS protocol.
alarm function
Equipped with abnormal alarm function, real-time alarm will be triggered when monitoring data exceeds the standard, monitoring function fails, communication interruption and other abnormalities occur. The alarm settings can be modified, and the alarm information can be transmitted remotely in real time.
Local display function
The lightning arrester action count is displayed using a 3-digit electromagnetic counter. The full current is displayed on a scale. The scale has a normal area (green), a caution area (yellow), and an alarm area (red).
