The transmission of reactive power in a power grid system reduces the quality of power grid parameters and causes voltage and active power losses in electrical systems. In order to prevent the adverse phenomena related to the transmission of reactive power in power grids, reactive power compensation systems are used near the locations where reactive power is generated.

The ZPUE S.A. company provides solutions for reactive power compensation in its offer. One of them is a concrete container station equipped with a set of protections and an MV capacitor bank with protective reactors.

The catalogue presents example substation configurations.

Detailed selection of MV switchgears and their equipment is listed in chapters dedicated to individual devices in the catalogue. The possibility of installing other types and configurations of switchgears should be arranged every time with the substation manufacturer.
