Powerline tech adds data to busbars
Siemens has used powerline communications technology to add data capabilities to its busbar systems to connect power systems to the Internet of Things (IoT).

The powerline technology allows the D2, LD, and LI busbar trunking systems to transmit not only current but also data so that an additional data cable is no longer needed. The powerline module is integrated into the tap-off units along with communication-capable protection, switching and measuring devices. Measured data, such as power, current, and diagnostics information can then be forwarded to higher-level automation and energy management systems via the conductors on the busbars.

The powerline module is integrated into the tap-off units along with communication-capable protection, switching and measuring devices. It can be connected to the busbar system with plug and play functionality. Measured data, such as power, current, and diagnostic information – such as switching cycles – can then be forwarded to higher-level automation and energy management systems via the conductors on the busbars.

"Our goal is to fully tap the potential of digitalization for electrification, from planning and installation to operation and maintenance," said Stephan May, CEO for Medium Voltage and Systems within the Siemens Energy Management Division. "We are continuing to further develop our technologies for this purpose. I am pleased that powerline technology now enables us to offer two functionalities in one system for the first time, making use of the Sivacon 8PS portfolio even easier and more flexible for our customers."

Busbar trunking systems are known for their ability to effectively, flexibly, and safely transmit and distribute current. With a cable, the power supply to adjacent machinery first needs to be disconnected when modifying an automotive production line, for instance by adding new pieces of equipment. Only then can the complex changes to the cable installation be carried out. With busbar trunking systems, the power tap-off units can be modified, added to, and replaced even while energized if necessary.

The new integrated powerline technology now allows busbar trunking systems to transmit not only current but also data. Transmitting current and data in parallel over the same system
