Determination of Optimal Options for Connecting and Combining Compensating Devices in an Electrical Network with a Voltage of 0.38 kV

The results of experimental studies of various options for connecting technical means for limiting current in the neutral wire to the physical model of a 0.38-kV network are presented. During the study, both the places of connection of technical means to the network and various combinations of their connection to the network model varied. A transformer with a “star/double zigzag with zero wire” winding connection scheme, a “star with zero wire/triangle” transformer group and an inductive coil were considered as technical means. Based on the experimental results, conclusions were drawn about the most rational switching location and the combination of technical means in the 0.38 kV network at asymmetric and nonlinear load.
