Synchronous close capacitor bank switching made easy SmartClose Synchronous Close Capacitor Switches Streamline project commissioning, calibration, and setup time. Trinetics® synchronous vacuum capacitor switches bring new focus to the synchronous close and zero voltage close capacitor bank-switching applications. Commissioning time, complexity and cost have been greatly reduced, while the precision and reliability of close on wave form switching has been substantially improved. Automatic self-calibration and durable, restrike-free, maintenance-free switching are just a few of the benefits gained by adding Trinetics® SmartClose synchronous vacuum switches to your capacitor bank applications. The UltraVac family of vacuum capacitor switches fully conforms to ANSI Standard C37.66-2005. • Exceptional reliability and durability in synchronous close and zero voltage close applications • 200A & 400A rating options • 15kV & 25kV; 110kV & 125kV BIL • Best in class C2 re-strike free • Long life vacuum interrupter with solid-dielectric insulation for maintenance-free switching • Eliminate the material cost and space required for inrush reactors • Mitigate harmonics and switching disturbances that occur in back-to-back capacitor bank switching and large power capacitor bank switching • One tank device configured for independent pole operation for three-phase applications Features: • Vacuum interrupters • Integral voltage sensors • Manual handles and position indicators Features: • Multi-pin connector for close/open command from cap control • Multi-pin connector for aux supply • Fiber optic port for waveform download Convert any bank to synchronous close. The unique design of the SmartClose capacitor switch includes six integral voltage sensors that detect the voltage waveform on both the capacitor side and the source side of each interrupter. A close command issued by a separate capacitor bank controller causes the SmartClose capacitor switch to close each interrupter independently when the voltage difference across each interrupter is zero. A simple close command to the SmartClose will initiate 3 phase zero voltage closing in all circuit configurations. Delta, Wye, Ungrounded Wye, and phase rotations are no longer a concern to the installer. Zero close functionality is embedded in the SmartClose switch and is enabled and calibrated prior to shipment. This allows the user to separately select a preferred capacitor bank controller with a range of functionality ranging from lower cost Volt-Time controls such as Trinetics’ ProCap C150T, to our ProCap C2000 VAR controls. Or alternatively, the switch can be remotely controlled through a separately supplied RTU/PLC controller. The bottom line? The bank controller decides when the capacitor bank is needed; the SmartClose switch receives that command and performs the synchronous close automatically. Key features of the SmartClose capacitor switch. Feature Function Benefit Internal CPU Self-calibration and configuration Plug and Play functionality reduces setting complexity and commissioning time. Six embedded voltage sensors Auto detects system parameters critical to proper waveform switching Reduces site installation costs, set up time, and total commissioning time. Eliminates the need to input phase rotation or system configuration and grounding. Loss of voltage trip Removes cap banks from service during a reclosing protection sequence or during a sustained outage Eliminates heavy inrush incurred when capacitor banks remain on line during a reclosing protection sequence or during service restoration. Constant current supply Compensates for internal temperature variations in key switch and drive system components Eliminates “drift” and maintains best-in-class waveform close accuracy. Switch fiber optic diagnostics port Provides access to waveform capture files for downloading and analysis Allows performance verification of waveform close accuracy without the need for expensive or bulky high speed recording equipment. Easy interface for capacitor bank controls Supports your chosen capacitor bank controller Use familiar legacy capacitor bank controls. Eliminates retraining associated with new capacitor bank controls. Performance Accuracy Successful close within 21˚ SmartClose 2˚ to 5˚ GY circuit, 23.9kV phase-to-phase, 200kVAr capacitors/phase.
