Electromagnetic processes in transformers during their disconnection by vacuum switches
The influence of the operation of vacuum switches on the electromagnetic processes of transformers of distribution networks has been studied. It is shown that during the disconnection of transformers from the network with the connection scheme of the windings "Wye/Wye, with neutral brought out for grounding" causes significantly higher multiples of overvoltages in the windings than the disconnection of transformers with the connection scheme of windings "Delta/ Wye, with neutral brought out for grounding".
