Enhance Control System and Monitoring Based on Star Delta Method

The control system on a 3-phase motor is essential because a 3-phase induction motor requires maintenance in its use. This is related to maintaining the age of the 3 Phase motor so that it is longer and more economical. The purpose of the research conducted by the researcher is to monitor the work of the 3-phase engine using the star-to-delta method using the ATmega16 microcontroller as a reader for changes from the star-to-delta process, which is displayed on the LCD (Liquid crystal display). The shift from star to delta method uses auto mode, which can set the transfer time using TDR (Timer Delay Relay). The results of the tests showed that the monitoring and starting system that has been designed could run as expected.
