Voltage drops in winter
Hello! Often the voltage jumps in the network (from 190 to 270 V). Gardening is connected from a step-down transformer 10KV / 3phase x 220V. Could this be from overload on one of the phases relative to the others (not all come in winter, and those who arrived can be connected in one phase)?

Hello! Yes, may be! Call inspectors, let them look for the reason. Most likely, more consumers are actually connected to one phase, which also include heaters and other powerful equipment. As a result of this, a phase imbalance occurs, voltage surges in the network.
