Abstract:
Induction motor is an efficient machine overcoming a wide range of industries now a days but due to heavy inrush current in the start up the current becomes high than rated current. Due to which it is started with a starter which reduces or limitize current. Up till now each motor has its own starter in all of the industries e.g. star delta starter is one of the most common starter used among other conventional starter that are soft starter, direct online starter, frequency starter etc. but there are some drawbacks of theses starters which makes them inefficient first drawback that there is a single starter for a single motor secondly these starters damages motor in most of the cases. Luckily there are certain techniques by which we can sequentially start more than one motors from a single Starter in a protected way which makes it cost effected because large number of starters are not required secondly implementation of our proposed starter is much simpler .This report gives us ideas that how we can use one starter for multiple motors.
