Utility Application Example

​

Delivering cost effective communications solution for utilities on medium voltage networks

​

e-terrapowercom uses power cables as a medium for digital communication necessary for automation and control of the power grid. The solution delivers a transparent IP network with Quality-of-Service (QoS) to prioritize critical applications, and uses Virtual LANs (VLAN) to separate data streams of each distinct service. In order to improve asset control and maintenance, IP video cameras and telephones can be deployed in key substations due to the exceeding bandwidth provided. The communication system can be rolled out over a large number of substations starting from High Voltage (HV) substation to several kilometers over the grid, as it does not require heavy civil works and additional infrastructure.

Industry Application Example

​

A flexible and cost-effective alternative for telecom infrastructure for industrial applications

​

Industries can take advantage of the power grid built to supply energy to production and machinery to create IP communication channels, using the e-terrapowercom solution. This data channel can provide backhauling for operating local networks, telemetry on remote devices, and supervision of the assets connected to the control center. In addition, environments like underground facilities often have limited radio coverage and Broadband Power Line enables connecting such areas.

E-terrapowercom Components

 

Long Range Version

The e-terrapowercom is also available in a long range version, which has a higher power density in shorter frequency channel to attain longer distances or overcome noisier environments. The maximum bandwidth is reduced and it is dedicated to specific cases.

 

Coupling Options

The e-terrapowercom modem is connected to the electrical grid through inductive or capacitive coupling devices. Inductive is used over insulated cables while capacitive requires a connection to a live part of the grid. Inductive is easy and fast to install, especially in cubicles and small rooms. Capacitive is mainly dedicated to overhead lines.
