Automatic low voltage capacitor banks are ideally suited for power factor correction at the main service entrance, in applications where plant loading is constantly changing. A microprocessor-based reactive power controller measures plant power factor via a single CT located on the bus/cable at the main service entrance terminal compartment, and switches capacitor stages in and out of service to track a user-selected target power factor. CT sold separately. Refer to CT Selection Guide on page 4-26. The AV4000 and AV5000 Automatic Capacitor Banks are designed for use in networks that contain little or no current or voltage harmonics.
Advanced Safety Features: The modularized compact design consists of a microprocessor-based controller with capacitor switching modules fitted into a cubicle arrangement for top entry. All power and control wiring is dead front construction. Capacitor modules consist of 3 phase dry metalized polypropylene elements. Each element has a nonreplaceable 100,000 AIR fuse and pressure sensitive interrupter. Capacitor modules feature a pre-charge circuit to reduce switching transients to 20% of that seen with standard capacitor banks. Internal discharge resistors reduce capacitor voltage to 50 Volts or less within 60 seconds. Dead front fuse holders on AV4000 & AV5000 have integral blown fuse indicators, standard. Cubicles are constructed with a locking door as standard and are furnished in a textured powder paint finish, color ASA 49 gray.

 |
Automatic C/K ratio selection |
|
Automatic CT polarity retrieval |
