The Viper-S solid dielectric, three phase recloser combines the time proven reliability of electronically controlled-vacuum fault interrupters with the maintenance benefits of a solid dielectric insulated device. Designed with a mechanically ganged operator for three-phase automatic or manual trip operation providing overcurrent protection for systems rated up to 38kV maximum, 800A continuous current, and 12.5kA rms symmetrical interrupting, making it an exceptionally reliable viper recloser option for modern distribution networks.
Viper®-S Solid Dielectric Three Phase Recloser
Features and Benefits
Reliable Configuration Pole mount, substation, and padmount configurations to fit a variety of applications.
Ease of Operation The Viper®-S is compatible with the SEL-351R, SEL-651RA, and SEL-751 controls along with a variety of other control options upon request.
Ease of Installation The Viper®-S is lightweight and compact. Site-ready designs provide all accessories preassembled prior to shipment, significantly reducing installation time.
Dead-Line Operation The unique design of the Viper®-S magnetic actuator system provides for local and remote operation of the recloser on battery backup in the event that the AC source power is lost or interrupted.
Reliable Performance Viper®-S reclosers utilize G&W Electric’s time-proven epoxy polymer system to fully encapsulate the vacuum interrupters. This system provides excellent insulation properties while providing fully shielded, void-free construction.
Controller Programming The controller is configured to meet the specific requirements of the application.
Power Grid Automation Ready The Viper-S is automation-ready, simplifying conversion for any future automation requirements.
Current Sensing The Viper®-S recloser has a dual-ratio current transformers for current sensing.
Dead-front Modules The Viper®-S dead-front modules are designed to fully shield energized components within the module assembly, enhancing linemen safety and reducing the risk of wildlife contact and wildfire ignition. External insulators remain energized as part of normal operation.
Frequently Asked Questions
What is a three phase recloser and how does it work?
A three phase recloser is an automatic switching device that detects and clears faults on all three phases simultaneously, improving system reliability and reducing outage duration.
What makes the Viper-S a reliable viper recloser for utility networks?
