Summary
●With its 3-in-1 Design Premset Switchgear is said to be the safest and most intuitive switchgear in its class:
- Breaking, disconnection and earthing functions are all integrated into a single compact three-position device, making it easier to operate.
-SF6-free design uses only vacuum and air technologies.
-Enhanced safety since it is fitted with failsafe interlocks.
● Additionally through advanced monitoring, control, and smart-grid functionality, Premset switchgear helps ensure your network is at its
peak performance level featuring:
- Feeder automation, with switchgear including built-in communication and local intelligence.
- Load management, with integrated smart metering
- Asset management, with advanced switchgear and transformer monitoring
- VIP Self-powered protection and communication relay for higher MV network availability
● With its standardized dimensions, reduced footprint and simple front power connections, both time and money spent installing Premset
Switchgear are greatly reduced. Every aspect of the system is designed with the intention of reducing total cost of ownership as well as
making installation and adaptions as seamless as possible.
● Premset switchgear is a technological breakthrough, opening the way to unprecedented safety, efficiency, and ease of use. It is safe and
reliable in any environment as insulation and screening of all live parts ensure a trouble-free service life, while SF6-free technology
enhances peace of mind. It is flexible, simple, modular, and functional; it is easy to install and easy to use, with operator-friendly
switchgear and no servicing of main units thanks to the SSIS technology.
