THE KYLE® NOVA-TS RECLOSER

Advances in Distribution Protection



Multi-Mode Configuration

The NOVA-TS recloser has the versatility of three modesof operation. Activation is easily configured using theForm 5 interface software via a personal computer.

Three-Phase Trip, Three-Phase Lockout (MODE A)

All three phases simultaneously trip on an overcurrent,reclose, and sequence together.

Single-Phase Trip, Three-Phase Lockout (MODE B)Each individual phase will sense line current and only thephase corresponding to the faulted phase will trip. If anyone phase sequences to lockout, the other two phases alsoopen, eliminating permanent single phasing of three-phaseloads.

Single-Phase Trip, Single-Phase Lockout (MODE C)

Each individual phase trips and sequences to lockout inde-pendent of each other. This is primarily for residentialloads and/or where single-phasing of three-phase loads isprotected by other means.

Selectable Phase Operation

The front panel allows the user to manually open and closany phase independently without menu navigation.Included are direct LED’s to include the mode of operationplus open, close, and lockout LED’s on a per-phase basis.

The operator phase select keys are now convenientlydesigned to agree with the trip mode selected, eliminatingconfusion or special operations. For example, if three-phase lockout is set, select-phase keypads will be activated

simultaneously causing all three phases to trip or closewith the manual trip and close pushbuttons. In single-phase lockout, manual closing or tripping is achieved byselecting the desired phase to close or trip.

Overcurrent ProtectionPhase Operation

In MODE A, all three phases trip simultaneously with aphase overcurrent.

In MODES B and C, each phase is allowed to operate on apre-programmed sequence to lockout up to four times,

with the protection parameters (minimum trip values,time current curves, reclose intervals, reset times, andsequence of operation) the same for all three phases.

Ground Operation

In MODE A, all three phases trip simultaneously with aground overcurrent.

In MODES B and C, all faults above ground minimum tripand below phase minimum trip will result in three-phasetripping. Phase and ground also share the same sequenceposition. As the sequence position advances, the phaseand ground TCC’s advance.

For faults above phase minimum trip, the Form 5/Triple-Single control only trips on the phase(s) above minimumtrip operating on the phase or ground TCC, whichever isfaster. Each ground sequence and TCC timing willadvance with the appropriate phase sequence for faultsabove phase trip.

Dynamic Phase Tripping

A new configurable option for Mode C operation is avaiable to trip and lockout all three phases in the event of aphase-to-phase or three-phase fault. Normal operationoccurs per the programmed sequence, but protection is

enhanced by interrupting all three phases, even non-faulted phases. Should a phase-to-phase or three-phasefault be detected on the system, all three reclosers willtrip and lockout whenever any one phase sequences tolockout. Three-phase lockout occurs if a multiple phasefault is present as the recloser advances to lockout. Forexample, when there is a phase-to-phase fault, the controwill trip and lock out all three reclosers when any onephase sequences to lockout; thus avoiding any multi-phase energization from one phase.

LED Status Indicators

Twelve LED’s display the status of each phase forimmediate analysis of the recloser and distribution line.No delays to scroll through LCD menus or selectorswitches for this vital information. Each phase includesclosed, open, and lockout LED’s with the close and openLED’s based upon circuit continuity in the closed andopen circuit. The trip and close monitor circuits provide

additional positive confirmation that the recloser willtrip or close respectively upon command. Each phasealso includes its own lockout LED which indicates thatthe recloser has completed its sequence of operationsand no further reclosing will occur.

Avoid any confusion on the configured mode of theNOVA-TS recloser through these three separate modestatus LED’s.

• One-Phase Trip - One-Phase Lockout

• One-Phase Trip - Three-Phase Lockout

• Three-Phase Trip - Three-Phase Lockout

These direct LED’s are used with each individual phaseLED’s to quickly understand why one, two, or all threephases are open. As an example, in one-phase trip/one-phase lockout mode, after a permanent fault on A-phaseonly, only A-phase will be open and in lockout, while both B- and C-phases will be closed.

Hot Line Tag

Hot Line Tag functionality will provide automatic three-phase trip/three-phase lockout operation independent of the mode selection. Hot Line Tag is usually activated when

live-line work is being performed and will trip all phases

on the programmed TCC for a fault on any phase. HotLine Tag also disables any reclosing of any phase. By trip-ping all three phases, even in single-phase trip/single-phase lockout, the circuit is permanently opened when an

unexpected fault occurs.

NOVA-TS SCADA and Substation Automation

NOVA-TS Triple-Single Recloser Substation Application

For new substations or upgrades to your existing substation, the NOVA-TSrecloser provides a cost-effective solution for your protection, metering,and communication applications. Whether your substation is primarilysingle-phase or three-phase, the automation features of the Form 5/Triple-Single control will improve your substation performance. Add the remoteoperation, status, and analog metering functions to your automation sys-tem through standard industry protocols for real time system analysis andoptimization. The light weight of NOVA-TS may allow retrofit to anyexisting structure without the expense of foundations and other structural

changes.Traditional single-phase hydraulic reclosers, the staple of the industry,provide essential fault protection. NOW this same design and manufac-turing expertise is available for your automation applications. One controlfor three reclosers; flexible coordination; advanced event recorder/dataprofiler analysis tools; and voltage, current, and harmonic metering–allcombined in the industry’s leading software–allows modernization of your substation applications.

Multiple fault scenarios were analyzed to provide propersystem coordination for both phase and ground faults.Phase-to-ground, phase-to-phase, and three-phase faults,along with multiple faults on different phases, were stud-ied to verify the correct sequencing of each recloser withproper time-current curves. As an example, loadside fuse

protection is maintained even if two faults occur on dif-ferent phases prior to resetting the control.

Should problems occur, utility operators would discovergreat benefits in repairs made on an individual phase basis. Replacement of individual phase devices bringslower inventory economics and shorter system restora-tion and bypass intervals.

A permanent fault at F1, followed by a transient fault atF5 prior to reset of Recloser A, would result in operationas described in Lines 1 and 2 of the chart below.

Line 1 summarizes the operation for a 300 amp perma-nent fault at F1; Recloser A operates twice on the fast

curve (TCC 106), followed by the fuse operation to clearthe permanent fault.

Prior to the reset operation of Recloser A, a 300 amp transient fault occurs at F5.

Line 2 shows a single trip operation of Recloser C on thefast curve to clear the transient fault. It then recloses torestore service without a fuse operation or unnecessaryoutage.

Different operating modes can be compared for any fauloccurrence as described here for a permanent fault of 300amps line-to-ground at F2.

Line 3 shows Mode A operation. All three phases openfor each trip and all three phases lock out.

Line 4 shows Mode B operation. Recloser B operates foutimes to lockout with Reclosers A and C also locking outon the fourth operation.

Line 5 shows Mode C operation. Recloser B operates foutimes to lockout while phases A and C remain energized
