Detailed introduction

OVERVIEW

Comprehensive pole-mounted capacitor bank solutions can be tailored to meet customer application needs. This customized bank package offers overall system improvements such as improved power factor, system capacity release, loss reduction, voltage stability, improved power flow and cost savings.

The pole-mounted capacitor rack frame is manufactured from high strength  galvanized steel frames .

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 singlephase 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.

The Edison capacitor switch incorporates superior insulating materials capable of withstanding severe electrical-mechanical conditions and is uniquely suited for demands of capacitor switching.
