The GN3E, GN3VE, GV, and GW sectionalizers are three-phase devices that automatically open all three phases simultaneously for either phase or ground faults. Sectionalizers, combined with a three-phase electronic recloser partner, provide a fully automatic economical solution for fault isolation. While the upline recloser trips on the fault current, the electronic sectionalizer provides a counting operation to isolate the fault during a reclose (open) interval of the upline recloser. The electronic sectionalizer provides a low-cost, flexible solution to improve the SAIDI reliability indices by isolating faults automatically without expensive alternatives. Sectionalizers are designed for radial systems for maximum coordination benefits.
A low-energy tripping mechanism operated by the electronic control initiates opening. Opening energy is provided by springs, charged when the sectionalizer is manually closed. No battery or external power is required for the GN3E, GN3VE, GV, or GW sectionalizers.
The electronic control provides the operating logic for automatic opening. Close is accomplished by manually closing the yellow operating handle under the sleet hood. The sectionalizer can also be manually opened with this handle which also provides a positive visual indication of contact position.
GN3E, GN3VE, GV, and GW sectionalizers contain count-restraint and inrush current features. These features prevent the sectionalizer from counting fault currents interrupted by a downline protective device and prevent the sectionalizer from counting on inrush current.
