Abstract
This project presents a Star Delta Starter (SDS) using Programmable Logic Controller (PLC) and current transformer for efficient control of induction motors in industrial applications. The PLC executes a programmed logic sequence, seamlessly transitioning the motor from star to delta configuration after sensing the current. This not only reduces the starting current, minimizing stress on the electrical system, but also enhances safety and efficiency. In this project the basic concepts of Programmable logic controller (PLC) and its applications are discussed. The hardware set up of 3 phase star delta starting of induction motor using PLC is implemented. Both the description of hardware and software is presented in this project. The flexibility and efficient controllability of plc helps in the growth of automation. Most induction motors are started directly on line, but when very large motors are started that way, they cause a disturbance of voltage on the supply lines due to large starting current surges. To limit the starting current surge, large induction motors are started at reduced voltage and then have full supply voltage reconnected when they run up to near rotated speed.
