ZDDQ products offer a power quality solution, which allows users to select features to meet their applications needs. The capacitor bank offers customers system benefits such as:

• Improved Power Factor

• System capacity release

• Reduced losses

• Improved power flow

• Cost savings

The pole-mounted capacitor rack frame is manufactured from high strength 6061-T6 aluminum alloy to reduce weight and allow for easier handling and installation. Stainless steel or galvanized steel frames are available on request. Capacitor rack frames for 15 kV class systems are available with 95 kV and 110 kV BIL insulation levels and accommodate three, six, nine or twelve single-phase capacitor units. Capacitor rack frames for 25 kV and 35 kV class systems are available with 125 kV and 150 kV BIL insulation levels and accommodate three, six, nine or twelve single-phase capacitor units.

Capacitor racks accommodate 50, 100, 150, 200, 300, 400, 500 and 600 kVar single or double bushing capacitor units in single row assemblies. Single-phase capacitor units can be connected in grounded-wye, ungrounded-wye or delta configurations depending on system parameters.

Capacitor racks are available in fixed or switched configurations to meet load flow requirements. Switched capacitor racks have been expanded to include Zero Voltage Closing (ZVC) ideal for loads adversely affected by transients caused by energizing capacitor banks or applications where inrush current and frequency may impact scope of supply.
