This article analyzes the transmission of storm surges in the network 0.38 / 0.22 kV neutral to earth through the power transformers 6-35/0 , 4 kV winding connection with the scheme "triangle -star with distributed neutral ." Proposed equivalent circuit for cases falling storm waves on the three phases simultaneously and fall of waves on one phase. The article can be useful to specialists in the field of electromagnetic compatibility.

Keywords: spectrum surges, connection diagram of the transformer windings, zero sequence currents, channel zero sequence equivalent circuit of the transformer.
