Power Line Carrier
General Information
- Description
The digital power line carrier system PowerLink from Siemens uses the high-voltage line between substations as a communication channel for data, protection signals and voice transmission. This technology, which has been proven over decades and continuously adapted to the latest standards, is employed for the following applications:
- As communications system for linking substations where there is no fiber-optic link available and where it would not be economical
- As backup system for transmitting the protection signals, in parallel to a fiber-optic link
