Gradual Generation Change
In the course of expanding the capacity, the power station of the Mainova Aktiengesellschaft in Frankfurt am Main received a modern Profibus-based electrical engineering in addition to new turbines. Ritter Starkstromtechnik supplied a medium and low-voltage switching system for this.

Safe airport link
Since 2006, passengers at the Pearson International Airport of Toronto, Canada, can enjoy the Cable Liner Shuttle as a high-speed and comfortable link between the new T1 terminal building, the T3 terminal and the parking area. As a part of the electrical equipment of the mass transit train that has been jointly developed by Siemens and the Austrian company Doppelmayr Cable Car GmbH & Co. (DCC), Beta low-voltage line protection switchgear ensures the safety of people, equipment and motors.

Four ways to success
Beta low-voltage circuit protection offers a broad overall spectrum for residential buildings just as much as for non-residential buildings or industrial applications. Be it protection, switching, monitoring or measurement - Beta always has the suitable device, the advantage for users being that they can rely on one single supplier.

New technology for proven systems
New purchase or retrofit, i.e. partial or complete modernization - economy plays a key role in this decision. A retrofit is often much more economical than a new purchase in cases where the mechanics of older machines are still in a good to very good condition but the automation and drive technology is no longer state-of-the-art.

Less Maintenance Effort with a New Drive Technology
Sinamics G150 frequency converters regulate the air stream of the suction draught fan in the Steag power station in Lünen. They ensure a high regulating accuracy, operation which is kind on the system, low maintenance and low energy requirement. In order to comply with the regulations for power stations, series connected line harmonics filters in these 6-pulse devices reduce the low frequency mains feedback to a level which can otherwise only be achieved by 12-pulse devices.
