0.38 kV electrical network with three-phase loads and capacitor shunt-balancing device

The issue of reducing the current asymmetry coefficient and the current unbalance coefficient (in the absence of KSHSU, KSHSU in the load node, KSHSU on transformer buses) with the help of shunt-balancing devices is considered. The proposed symmetrical device has an additional two power stages and allows to increase the efficiency of symmetry due to adjustable, automatically changeable parameters that vary depending on the level of current asymmetry, i. e. on the magnitude of the zero-sequence current.
