Compact open rack banks for reactive power compensation

Shunt capacitor banks are primarily used to improve the power factor in the network. They also improve the voltage stability and reduce network losses. Improving the power factor also means a higher power transmission capability and increased control of the power flow.

Hitachi Energy’s open rack capacitor bank QBank is available with internally fused, externally fused or fuseless capacitor units. The major advantage of QBank is the compact design, small footprint and easy maintenance.
