Capacitor Reactor Installation
capacitors are 100 kvars, 200 kvars, and 300 kvars, up to 600 kvars. Units of less than 100 kvars are also available. If there is more than one capacitor in each leg, the capacitors are connected in parallel. For capacitors in parallel, the kvars are additive so that a bank with two (2) 200-kvar capacitors per phase would be a 1200 kvar bank. - Download [PDF]

Shunt reactor fundamentals: Connections in the substation ...
1. Introduction to shunt reactors. Shunt reactors are used in high voltage systems to compensate for the capacitive generation of long overhead lines or extended cable networks.The reasons for using shunt reactors are mainly two. The first reason is to limit the overvoltages and the second reason is to limit the transfer of reactive power in the network.
QCap Low voltage capacitors for improved power quality
In order to protect capacitors against harmon-ics, the installation of a detuning reactor in se-ries with the capacitor is strongly recommend-ed. This reactor will increase the impedance for the high frequencies and will limit the current flowing into the capacitor. We usually protect the capacitor from the 3rd harmonic upwards
