Open Rack Capacitor Banks are primarily large installations used to improve the power factor of an entire electrical network. They improve voltage stability and reduce network losses. Improving the power factor also means a higher power transmission capability and increased control of the power flow. Capacitors are installed in welded galvanized steel or aluminum racks. Racks and capacitors are shipped ready for field installation as a turnkey package including supporting insulators, substructures, connecting bus, wire and other accessories for a complete three phase system. Harmonic filters are also available.
