Gridcom T390 Universal Power Line Carrier (PLC) for High Voltage (HV) Transmission Lines
GE's Gridcom T390 is an integrated system, combining high performance and flexibility, which allows utilities to reliably transmit voice, data, teleprotection and other services over HV transmission lines.
Using the Power Transmission Line as the Transport Medium
Electrical utilities need to exchange information regarding their electrical network in an efficient and effective manner, while preserving their initial investment. Despite the growing use of digital communication systems, communications over power line is still often the most cost effective and reliable solution. Using power lines as a communication medium allows the operator to have full control, without the associated costs of renting a dedicated communication line from a telecom operator. GE's Gridcom The Gridcom T390 is designed to be is a completely integrated universal analog and/or digital power line carrier. Engineered for power utilities' environments and constraints, Gridcom T390 provides a dependable communication link in the most demanding substation conditions. The Gridcom T390 is designed to be a robust back-up solution for critical services, and an Ethernet bridging solution to substations with no optical fiber access.Key Benefits
