AUTOVAR ® MV FILTER

AUTOMATICALLY SWITCHED MEDIUM VOLTAGE HARMONIC FILTER/POWER FACTOR CORRECTION

http://www.comsprague.com AUTOVAR® MV FILTER BANK Automatic Power Factor Filter Systems

Harmonic compensation and power factor correction system for medium voltage applications with auto- matically switched capacitor stages. • Programmable solid state power factor controller that automatically adds or subtracts capacitor banks to maintain preset target power factor. • Reactors specifically designed for de-tuned, tuned and high pass filter. • Separation barrier between higher operating FEATURES AND SPECIFICATIONS: temperature harmonic reactors and heat sensitive capacitors. CONFIGURATION: Cabinet: 11 Gauge, seam welded NEMA 1, 3R, or 4X : APPLICATIONS ratings; ANSI gray — 61 corrosion resistant enamel; The MV Filter Bank is designed for commercial and Forced air ventilation; Sloped-roof enclosure design industrial power systems to improve power factor, for channeling snow and water; Cubicle doors with reduce harmonic distortion, increase system capacity, view ports at main disconnect switch, ground blade, and improve voltage regulation. Autovar-MV Filter capacitor section; Moisture and varmint resistant Banks are power quality devices which reduce base channel design. harmonic distortion (current or voltage), improve Fusing: Main fuses (50KA) for fault current detection power factor, provide voltage support, and increase and overcurrent protection. Individual capacitor cells system capacity. protected with explosion resistant fuses. Harmonic reactors: Tuning reactors custom designed to commercial and industrial applications. Sizing usually results from harmonic spectrum analysis of field measured data. Interrupting device: Vacuum Contactors (oil optional, breaker extra). Keyed Interlock: Standard keyed interlock system interconnects main and ground switch as well as capacitor and reactor cubicle doors. Blown fuse detection: Instrumentation panel light provides alarm status indication for unbalanced neutral voltage or current. Indicator of individual blown capacitor fuses is based on solid-state, microprocessor overcurrent relay. Ground switch system: Visual safety indication through cubicle view ports. Interlockable switch applies solid, safety ground to electrically continuous ground bus to provide additional de-energizing of individual capacitor cells. Controls • Solid state power factor controller with micro- processor and liquid crystal display for power factor metering and indication of energized capacitor stages. • Micro Programmable Logic Controller for sequencing, timing, and controls. – Time delay (5 minutes typical) for capacitor discharging, capacitor settling or restrike duration.

- 2 - CAPACITORS: • Low loss, all film/foil capacitors • Stainless steel tank and mounting brackets with a light gray finish • Non-PCB dielectric • Internal discharge resistors
