VFI single-phase pad-mounted transformer
Eaton’s Cooper Power series VFI single-phase pad-mounted transformer combines voltage transformation and sectionalising in a compact, money-saving package. Delivering comprehensive system protection, the vacuum fault interrupter transformer enables utilities to dramatically reduce the duration and scope of outages while optimising performance.
Reduces the number of customers impacted by an outage by up to 50%
Cuts time required to locate a fault by up to 50%
Provides ultimate reliability and flexibility through an extensive range of programmable controls and settings
Ideal for residential applications where space is limited or inline fault or radial tap protection is difficult
VFI sectionalising capabilities deliver superior system protection
Slashes installation costs, complexity and space requirements compared to separate single-phase transformer and switchgear installations
Helps improve SAIDI and SAIFI metrics
Utilises industry-standard protection schemes to deliver unparalleled transformer overcurrent and fault protection
Provides ease of use with resettable breaker operation, programmability and coordination with upstream and downstream protection devices
Offers safety and security with deadfront construction, coupled with aesthetically pleasing, low-profile Shrubline (ANSI Type-2) design
Meets or exceeds industry standards including ANSI, NEMA and DOE energy efficiency standards
Decrease the duration and scope of outages
The VFI transformer is capable of isolating faults up to 50% faster than conventional fused equipment – and can cut the number of affected customers in half. By dramatically reducing downtime, the VFI helps utilities enhance customer satisfaction.
Get more protection in less space
Only Eaton combines a transformer and sectionaliser in the smallest possible footprint, providing unparalleled reliability for underground systems with faster installation at a lower overall cost.
One solution, multiple applications
The VFI transformer easily coordinates with upline and downline protective devices as system changes occur. Use to tap off a main underground feeder; in place of a three-way junction cable; to sectionalise points on a long or densely loaded feeder; in high potential cable failure areas; and as a tie point between two systems.
