Low Voltage Feeder Monitoring Device - Communication Unit

Product Description

Low voltage feeder monitoring device - communication unit 1.Product profile
The low-voltage feeder monitoring device consists of a communication unit, a power module, and a monitoring unit. The communication unit is generally installed in the distribution cabinet, column mounted JP cabinet, or low-voltage cable branch box. It serves as a data aggregation gateway to achieve upstream communication through carrier modules, communicate with downstream monitoring units through CAN bus, and achieve local maintenance of the system through Bluetooth interface. The number of monitoring units that can be connected is not less than 64; The power module provides DC power, CAN bus, and sampling voltage to the monitoring unit through a cascaded interface. A single power module can be connected to no less than 10 monitoring units; The monitoring unit is connected to an external current transformer to achieve current detection function, connected to the voltage sampling signal output by the power module to achieve voltage detection function, connected to a switch input to achieve station status monitoring, with functions such as topology characteristic signal transmission, characteristic signal analysis, and phase sequence recognition.
