Розробка лабораторного стенда для дослідження систем водопостачання (електрична частина)

Abstract

The laboratory stand for the study of water supply consists of three parallel-connected circulation pumps. The stand provides possibility of work in different modes. Speed electric pumps is regulated by various methods: by switching the motor windings by changing phase voltage using a laboratory autotransformer, by changing the frequency of the supply voltage.
