CONFIGURATION: Operation: Autovar harmonic filters are designed to be sized as any power factor correction unit. In most low voltage applications where harmonics are generated by 6-pulse devices, no harmonic audit is necessary to design the Autovar filter because it is already designed for the worst case environment at the KVAR size specified.
Layout: Two cabinets. Reactors and optional disconnect in one cabinet isolated from heat sensitive capacitors and controller which are in a separate cabinet. This design simplifies maintenance and troubleshooting
Cabinet: 12 gauge steel with Siemens grey, baked enamel. Lift bolts standard.NEMA1.
Power line interconnect: Rugged, copper bus bar connection with access provided for top or bottom entry. All internal power wirin connections from bus are laid out on a most direct basis with minimum bends for ease of troubleshooting.
Modular tray design: Capacitor banks arranged in modular trays withcapacitors, fuses, blown fuse indicating lights, contactors and control fuses grouped in a logical, easily understood layout. This permits easy access, quick identification of operating problems and ease of expandability
Fusing: UL recognized, 200,000 amp interrupting capacity provided on all three phases of each bank. Blade-type fuses mounted on insulator stand-offs.
Blown-fuse lights: Blown fuse indicating lights located on the door and at individual fuses to facilitate tracing of cleared fuses. Push to test: Allows testing of door fuse indicating lights.
Auto Locate: When door is open and bus energized, fuse circuit automatically checks for cleared fuses. If a fuse has cleared,the light atthatfuse comes on for easy troubleshooting.
Door interlock: Door interlock automatically turns off control circuit when engaged. Power continues to be provided to the unit until disconnect is open.
Warning: Bus bars are still live when door interlock engaged.
Interwiring: On-site interwiring of multiple cabinet design is made simple by prenumbered bundles and clear diagrams.
Exhaust fan: Two fans per cabinet provide thermal protection for both capacitor cabinet and reactor cabinet.
- Moulded case circuit breaker
- Fused disconnect switch
- Weather proofing provides NEMA3R rating
