In addition, the grounding transformer has electromagnetic characteristics, and has high impedance to the positive sequence and negative sequence currents, and only a small excitation current flows in the windings. Since the winding directions of the two windings on each iron core column are opposit... read more
The grounding transformer is specially designed for the arc suppression coil. Generally, the arc suppression coil is installed on the triangle side of the transformer of the small current grounding system to compensate for the grounding capacitance current when the power grid is single-phase grounde... read more
The classification of commonly used transformers can be summarized as follows: 1. According to the number of phases: (1) Single-phase transformer: used for single-phase load and three-phase transformer group. (2) Three-phase transformer: used for raising and lowering voltage of three-phase system. S... read more
