Diagnostic PLC modems
for medium-voltage lines and devices
(35 kV version on request)
MV line diagnostics
The core function of the modem is the comprehensive diagnostics of both medium-voltage lines and connected devices (e.g. transformers). This feature is based on capturing and processing of partial discharges.
Reliable communication channel
The modem utilizes proven G3-PLC standard as the main communication channel. Both manual and automatic adaptation of the PLC channel settings are enabled to achieve optimal speed/robustness ratio under all conditions on the powerline. The auto routing feature allows you to easily create a large network and manage it from single node – network coordinator. Each operation in the network is in accordance with Cyber Security rules (encrypted, authenticated).
Extremely robust PLC standard MTEC offers (thanks to an ultra-narrowband modulation scheme) the ability to communicate at a distance of many tens of kilometers without the use of any repeaters.
The modem is produced in the following variants:
- MT-MVPLC1 – full-featured modem with advanced diagnostic functionality based on a partial-discharge analysis
- MT-MVPLC1-S – modem with advanced communication features
- MT-MVPLC1-R – modem with basic communication features
