Text version of the page
The GVS-C is part of the award winning GVR family and combines the
high reliability of vacuum interruption with the controlled environment and
high dielectric strength of SF6, in a compact, maintenance-free unit. Since
SF6 is only used as insulation, there is no health hazard from toxic byproducts
of arcing.
GVS-C Current
Sectionaliser
For Pole Mounting and Substation Applications
The GVS-C is a stand-alone, circuit-opening device, which can be used in
conjunction with source side reclosers or reclosing circuit breakers to
automatically isolate the permanent faults and confine the outages to a
smaller section of line. The power required to operate the control circuitry
and mechanism is obtained from the line via a single phase auxiliary
voltage transformer.
Application
Key Features
» Superior, proven Fit & Forget technology with minimal
maintenance
» Environmentally friendly vacuum interruption
produces no by-products
» The lightweight corrosion resistant aluminium tank
makes the GVS-C easier to transport and install
» The EPDM or silicone bushings are tested for
tracking and erosion to IEC 61109 and are resistant
to damage from vandalism or mishandling
» Endurance tested to 10,000 operations
» Bi-directional - senses fault current in either direction
» Can be upgraded to full auto-reclosing circuit
breaker*
» The unit (GVS-CR) can be supplied complete with an
RTU to allow the sectionaliser to be remotely
controlled or with the facility to allow the customer to
install their own purpose built RTU
» Fully user configurable settings including:
- Number of faults to lockout, 1, 2 or 3
- Adjustable phase fault setting 10 to 630 amps
in 10 amp increments
- Adjustable Earth fault setting 5 to 325 amps in
5 amp increments
- Adjustable reclaim time 15, 30, 60 or 120
seconds
* Note: Please specify when ordering to ensure the unit has the
relevant facilities installed prior to despatch to allow upgrade to a
full auto-recloser.
The patented, single coil magnetic actuator provides consistent performance
and a dramatic reduction in moving parts. Materials and finishes have been
carefully chosen for reliability – from EPDM bushings, tested for tracking and
erosion to IEC 61109, in salt, fog and other environments, to the neodymium
iron boron permanent magnets used in the mechanism.
