The article deals with the calculation technique for determining the number of self-starting pumping units depending on the network voltage setting and the main design dependencies of the self-starting process of electric motors fed from a three-phase three-winding transformer, and a replacement circuit for one phase of the circuit is made up. Technical solutions for the modernization of pumping units are proposed, which allow the application of the self-starting mode at reclamation pumping stations.
