1 TripSaver II Cutout-Mounted Recloser For enhanced lateral circuit protection at 15 kv and 25 kv
2 Introducing s new TripSaver II Cutout-Mounted Recloser: A better solution for overhead lateral circuit protection at 15 kv and 25 kv Conventional lateral circuit protection requires some concessions Over 90% of temporary faults on overhead distribution circuits occur on laterals. Over the years, utilities have dealt with lateral protection a couple of ways. Some utilities employ a fuse blowing philosophy: The substation feeder breaker is properly coordinated with the lateral fuse, so that the fuse will clear any downstream fault within its rating... not the breaker. The problem: Service to customers on the lateral is permanently interrupted even for a temporary fault as shown in Figure 1. And the utility must deal with the high cost of service calls to replace lateral fuses. Feeder breaker Temporary or permanent fault Lateral fuse Feeder breaker Temporary fault Figure 1. Fuse blowing philosophy. Lateral fuse Other utilities employ a fuse saving philosophy: The first trip of the substation feeder breaker is intentionally miscoordinated so that the breaker operates faster than the lateral fuse to clear a fault downstream of the lateral fuse. The second trip of the breaker is slower so that if the fault is still present, the lateral fuse will operate to clear it. The problem: All customers on the feeder experience a momentary interruption for all faults as shown in Figure 2. Figure 2. Fuse saving philosophy. TripSaver II provides better lateral protection s new TripSaver II Cutout-Mounted Recloser eliminates these problems. It s ideally suited for protection of laterals that experience frequent temporary faults. This self-powered, electronically controlled, single-phase vacuum fault interrupter is available for installation in new or existing currentproduction ( -R10 or -R11 ) or MacLean Power Systems Type XS Fuse Cutout Mountings. A twoinsulator, branch-feeder style mounting is also available. TripSaver II eliminates the permanent outage which results when the lateral fuse operates in response to a temporary fault. Utilities using fuse blowing will see an improvement in SAIFI without sacrificing MAIFI. And TripSaver II eliminates the momentary interruption on the feeder in instances where the breaker is tripped to save the lateral fuse during a temporary fault. Utilities using fuse saving will see an improvement in MAIFI without sacrificing SAIFI. 2
3 TripSaver II has been tested to, and is in compliance with, IEEE Standards C and C and IEC Standard TripSaver II is manufactured in accordance with a quality system certified to ISO 9001:2000. As shown in the following table, TripSaver II offers a number of advantages over traditional lateral protective devices. Comparison of Lateral Protective Devices Feature/Benefit Single-Phase Hydraulic Recloser Dropout-Style Electronic Sectionalizer TripSaver II Easy to install Low initial price Low installation cost Fault-interrupting capability Easy to reset Electronic control No bypass switch required Light weight compared to oil reclosers No battery backup required Fits in cutout mounting No momentary outage on the main feeder for lateral faults 3
4 TripSaver II s operating sequence TripSaver II supports up to three reclosing operations (four tripping operations in total) before it drops open. A wide variety of time-current characteristic (TCC) curves are available. The open interval between tripping operations is five seconds. The vacuum interrupter resets two seconds after TripSaver II drops open. The operator can then reclose TripSaver II into the mounting. In instances in which a temporary fault is cleared before TripSaver II reaches the end of its operating sequence, TripSaver II will revert to its first TCC curve, i.e., reset after 15 seconds have elapsed since the last reclosing operation. How TripSaver II works for a temporary fault Consider a temporary fault downstream of TripSaver II, as shown in Figure 3. Feeder breaker Figure 4. TripSaver II opens. After five seconds, TripSaver II recloses, restoring power to customers served from the lateral downstream, as shown in Figure 5. Since the fault was temporary and has been cleared, further tripping operations aren t needed. TripSaver II reverts to its first TCC after 15 seconds. TripSaver II Temporary fault Figure 3. Temporary fault. Utilizing its fast TCC curve, TripSaver II opens, as shown in Figure 4. Only customers served from the lateral downstream of TripSaver II experience a momentary interruption. Figure 5. TripSaver II recloses. How TripSaver II works for a permanent fault Consider a permanent fault downstream of TripSaver II, as shown in Figure 6. 4
5 Feeder breaker TripSaver II Permanent fault Permanent fault Figure 6. Permanent fault. Figure 8. TripSaver II recloses. As before, utilizing its fast TCC curve, TripSaver II opens, as shown in Figure 7. Again, only customers served from the lateral downstream of TripSaver II experience a momentary interruption. Since the fault is permanent, TripSaver II performs further tripping operations per the specified TCC curves. For utilities employing fuse saving philosophy, TripSaver II drops open at the end of its operating sequence, in the same manner as a standard fuse cutout providing visual indication that the faulted lateral has been isolated, as shown in Figure 9. The vacuum interrupter resets two seconds after TripSaver II drops open. TripSaver II may then be reclosed by the operator once the fault has been repaired. Permanent fault Figure 7.

Porcelain insulator shown; composite-polymer silicone insulator also available. NEMA Type B and Extended Mounting Brackets are available B Parallel-groove connector tin-plated cast red brass. For ease of connection, accommodates two conductors, even of unlike size D B A C Attachment hooks for Loadbuster Tool it also guides TripSaver II during manual closing E D Upper contact silver-to-silver; stainless-steel spring provides high contact pressure C E F Bumper and Retainer spring-loaded retainer and bumper dampen impact on closing, reducing the possibility of bounce-back Vacuum fault interrupter it is contained inside the upper housing G Trunnion high-strength cast bronze, silver plated. Surfaces around trunnion bear on broad hinge surfaces to keep TripSaver II in alignment during closing. Its special shape facilitates easy removal and reduces vibration F G H H Lower contacts silver-to-silver; provide dual current path, independent of hinge pivot I Mode selector for selecting automatic reclosing or non-reclosing operation. In nonreclosing mode, TripSaver II will operate oneshot-to-lockout, suitable for use when crews are working downstream of TripSaver II I J Liquid-crystal display screen displays TripSaver II status. Six languages are supported J Ice-Breaking Capability TripSaver II is capable of dropping open under ¾-inch (20-mm) ice formation. Sectionalizing Option A sectionalizing option is available for TripSaver II models rated 4 ka. If specified, TripSaver II will operate as a sectionalizer for faults between 4 ka and 6.5 ka. TripSaver II will count the number of operations of the source-side circuit-breaker or recloser, and drop open after the specified number of counts. The counter resets if no sectionalizing event is registered for 120 seconds. 6
