Topscomm medium voltage PLC system is composed of carrier host, carrier slave and coupler, widely used in electricity consumption information acquisition field and distribution network automation field.

TOPSCOMM Medium Voltage PLC digital Communication

Rack Type Application Mode

Install rack type PLC host in substation, and install PLC communication slaves along medium-voltage feeder line, to constitute substation-centered carrier communication network. This network is connected with transmission network in substation through Ethernet to constitute a safe and special access network for electricity information acquisition system and power distribution automation system.

Wall-mounted Type Application Mode

Available to settle the communication issues where wireless signal is not good or not covered.

In electricity information acquisition field:

Install PLC communication host in power line of good wireless signal, and install PLC communication slave in terminal point of bad or no wireless signal, to settle the problem that data cannot be read and collected due to bad or no signal in mountain area.

In power distribution automation field:

Under the circumstances that parts of power lines cannot be paved with optical fiber or parts of terminal points cannot be covered with wireless signal, install PLC communication host in main communication access point, and install PLC communication slave in difficult communication terminal point, to realize reliable communication connection between terminal point and main system.
