Power Survey Zero Voltage Crossing (ZVC) capacitor bank is a state-of-the-art microprocessor based control.  The purpose of the ZVC system is to virtually eliminate capacitor energizing transients by independently energizing each phase of the capacitor bank coincident with the occurrence of the phase’s zero system voltage reference point.

The expected benefits include:

• Increased “power quality” by utilizing capacitor switching with significantly reduced voltage spikes which are a nuisance to sensitive equipment such as computers and adjustable speed drives.
• Increased capacitor and switch life.
• Reduction of induced voltages into the low voltage control wiring.
• Reduction of station ground transients and reduction of distribution ground transients.
