Capacitor units should be capable of continuous operation up to 110 of rated terminal rms 5 voltage and a crest peak voltage not exceeding 2 x 2 of rated rms voltage including harmonics but excluding transients the capacitor should also be able to carry 135 of nominal current.
The reactive power supplied by the fixed capacitor bank is constant irrespective of any variations in the power factor and the load of the receivers.
