Ensto’s Auguste is a two-in-one solution: The versatile product includes both an automated load-break switch and a disconnector. This combination not only detects and isolates the faulty part but also manages and helps to reconfigure the medium voltage electricity network easier and faster during power outages. After having detected the fault in a couple of minutes, the product simultaneously allows the recovery of power supply in the remaining part of the grid. That, in turn, ensures the supply to end users. A full-load disconnection is enabled from 400 to 630 A of a 10 to 36kV line.
The reliable functioning of a switchgear is crucial when a fault occurs. The Auguste is designed to withstand even the most severe climatic conditions from -50°C to +55°C in all types of overhead line networks all over the world. Thanks to its high-quality materials, SF6 gas insulation optimization and extensive testing the device operates extremely reliably. Hence, it enables improved rates of the SAIDI and SAIFI supply reliability indexes.
Naturally, money is saved when the power is restored quickly after the fault appears. The Auguste is controlled remotely from a control center (SCADA), and as there is no need to travel to the faulty point, money and time savings are remarkable. Radio, GSM/GPRS and IP transmissions are used in accordance with several international communication protocols, and the cyber security aspect has carefully been taken into account.
The savings start at the moment of installation thanks to the integrated modular design. As the transformer is embedded in the SF6 chamber and the surge arresters are fitted on the tank just before installation, the assembly is always fast and easy, and takes only a half-day.
The maintenance-free Auguste is Smart grid compatible. Its automation, measurement and remote-control characteristics allow gathering data to be used in decision making and future planning. In principle the Auguste can be customized with almost limitless specifications and customer needs in accordance with the international IEC standards.
