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.
