Sturdy and stable substation automation
Bay station controllers in the electrical power supply must withstand special environmental requirements, especially when the station automation is used in high-voltage equipment, strongly vibrating or shock generating system components or also in environments with a seismic risk. We have therefore developed an extremely sturdy bay station controller with the net-line BCU-50, which fulfils the requirements of modern substation automation. Like all products from SAE IT-systems, the BCU-50 is also distinguished by high functionality and durability as well as tremendous performance.

Voltage and shock-resistant
The BCU-50 has been developed in line with the product standard DIN EN 61850-3. According to this standard, it is suitable for use in locations such as power stations and medium voltage stations “G”, high-voltage switchgears “H” as well as for signal and field connections “f” and high-voltage connections “h”. Thee dielectric strength of the bay station controller corresponds to Class VW3 as per IEC 60870-2-1. Also in respect to shock resistance (DIN EN 60068-2-6), vibration strength (IEC 60068-2-27) and seismic vibrations (EN 60255-21-3), the net-line BCU-50 fulfils the high requirements of the standards. Consequently the system can also be used in regions prone to earthquakes. The system cards designed for tough use in the rough environment of switching housings, transformer stations and high voltage systems enables safe operation.
Application fields of the BCU-50
A series of powerful functional modules forms the basis of the numerous possibilities for using the BCU-50. These include for example convenient cross-connection (of information between different telecontrol stations), as well as the integration of external components (for instance protective device coupling via IEC 61850 or IEC 60870-5-103). The main application fields of the BCU-50 are:
- Station and bay controller in medium and high-voltage switchgears
- Gateway and communication router between station buses, field bus and control systems
- Monitoring and control unit for the utilities, waste management and manufacturing industry
Just like its brother, the FW-50, a particular strength of BCU-50 lies in the implementation of communication tasks with substations and control systems of many different manufacturers
