Study of Automatic Phase Changer

Abstract

The security management of developing countries has introduced requirements for the use of computers in the era of electronic management. This automation is needed because control of energy costs has become very high. Many machines and products depend on energy management. If the conversion process is manual, not only will time be lost, but damage to equipment or systems may occur due to human errors during the conversion, leading to significant losses. Therefore, when an autotransformer is used to change a phase from a negative phase to an accessible phase, there is no need for time as the phase changes within a second.
The purpose of this article is to show the real concept of a programmable level switch for 230V-240V AC. However, most of the techniques are done in much the same way with a single-stage switch, two-stage programmed switches, and three-stage programmed switches, but this representation is explained by the programmed level change in the live environment as the three-level changes are now the control for the single- level output application.
