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

One of the main advantages of high voltage capacitor installation is that the losses in the step-down transformer are reduced. The cost of a high voltage capacitor scheme will be higher. As in the low voltage capacitor scheme, the possibility of over-compensation and resonance issues should be checked. A typical scheme is shown in Figure 8.
Abstract: Generating reactive power in a power plant and delivering the load over long distances is not economically acceptable, but this reactive power is simply provided by capacitors or excited motors in the load centers. The distribution system usually has two main problems, high power loss and poor voltage profile. One of the reasons for low power factor losses is that if the power
