2 Thereclosers are designed for threephase automatic or manual tripoperation providing overcurrent protection for systems rated up to38kV maximum, 800A continuous,and rms symmetrical interrupting. FEATURESR eliable performance -Viper-Sreclosers utilize G&W s time provenepoxy polymer system to fullyencapsulate the vacuum system provides excellent insulation properties while providingfully shielded, void-free modules are UV protected and100% factory tested for partial discharge. The Viper-S recloser utilizes the latest in magnetic actuator technology. The interrupterand actuator assembly are testedannually for 10,000 mechanical operations to ensure a long servicelife.

3 If AC power is lost, the recloserhas enough stored energy to triponce, after the control sends the tripcommand, within a 24 hour Flexibility - Viper-Sreclosers are designed to work witha variety of different controls including Schweitzer s SEL-351R,Falcon , SEL-651R, SEL-351S,GE s URC and others. Operator Safety -Vacuum inter-rupters are sealed within a soliddielectric insulation. A hookstickoperable manual trip and lockouthandle prohibits operation eitherfrom the control or remotely. Amechanical blocking device furtherassures against accidental closethrough the handle.

4 An open andclosed contact indicator verifies con-tact position. Contact status andlockout condition can also be verifiedat the - Solid dielectricinsulation provides a maintenance-free installation. Electronicequipment associated with theoperation of the magnetic actuator(s)are located in the of Installation - The Viper-S islightweight and compact. Site-readydesigns provide all accessories including bracket, arresters andvoltage transformers preassembledprior to shipment significantly reducing installation time. One sin-gle control cable brings all current,breaker status and trip/close information into the Flexibility - Units aredesigned for overhead, substationand padmount units can be equippedwith either horizontal or vertical insulators.

5 Removable silicone insulators are standard for overheadapplications. This feature permitseasy field replacement if an insulatoris damaged. Higher external BILrated insulators can also be retrofitted if Grid / Lazer AutomationSolutions - The Viper-S is automationready, simplifying conversion for anyfuture automation requirements. Amulti-ratio current transformer isencapsulated within the module. Thecurrent transformer is provided atratios of 500:1 and 1000:1. Inputs tothe control are field changeable. CT accuracy is +/-1%. Optional capacitive style voltage sensorsencapsulated within each modulepermit voltage reading for networkreconfiguration while eliminating theneed for add-on sensors and amplitude sensing accuracyto +/- 5% over the temperature range+65 C through -20 C when tested asa system.

6 External voltage and current sensors can also be useddepending on application requirements. Complete Lazer automation packages are available offering apre-engineered solution for applica-tions requiring intelligent automaticswitching and power restoration. Thepackages feature one or more pro-tective relays, (typically Schweitzer),equipped with distribution and com-munication capabilities.

A remote status signal reports the operationalstatus of the interrupter power supply permitting remote indicationof the control s capability to open orclose the recloser. Custom Relay Solutions (CRS) -The CRS option permits using48 VDC or 125 VDC control logicvoltage as an alternative totraditional 14-pin SEL, Cooper andGE controls which use 24 VDC forcontrol logic.

8 Recloser power is notaffected. This flexibility reducesinstalled cost for retrofit projects bylimiting the need to change relays orreplacing the input/output voltage sensing- Permitsvoltage reading for network reconfig-uration applications and provides asecondary analog 120V AC outputaccepted by most TRIP OPERATIONO peration of the hookstick operablemanual trip handle trips and locks outthe recloser. A contact position indicator is provided indicating openor closed status of the contact status is also displayed at the control. Operation ofthe manual trip handle disables anylocal or remote closing operation untilthe handle is reset.

9 A mechanicalblocking device further assuresagainst accidental close through thehandle. The handle is operable fromground level. Once reset, the recloser can be closed from thecontrol. CONTROL CONNECTIONST wist style connectors make cableconnection between control and recloser extremely easy. Thetraditional 14-pin recloser controlconnector design is the same asother Cooper style recloserspermitting easy change out of previously installed controls CAPABILITIESV arious style controls are availabledepending upon application require-ments. Typical control settingsinclude: Minimum trip for Phase , ground and sensitive ground faults.
