Electric Portal is about electrical concepts and other electrical machines like motor transformer,dol starter,star delta starter,auto transformer starter and much more
Different starting methods are used to start 3-phase induction motors like star delta starter, autotransformer starter, variable frequency drive, soft starter, and one of the starting methods used to start three phase induction motor is the DOL starter. DOL starter is also known as the Direct Online Starter because it directly apply full line voltage to […]
There are many different starting methods used to start a three-phase induction motor like Star delta starter. To start a higher rating 3-phase motor star-delta starter is used. wye-delta starter is useful where all six terminals of the motor are accessible. In this article, we will discuss the star delta starter working principle with the help of a power and control diagram, Theory, connection wiring […]
Autotransformer starter working pdf The squirrel cage induction motor started on full line voltage using D O L starter as a starting method draws a very large starting current which can damage motor winding and also create a current surge on the power system. Hence another starting method is used to start three phase induction motor called an autotransformer […]
What is a soft starter, application, and working principle pdf Soft Starters are starting devices, used for the acceleration, deceleration, and protection of the three phase electrical induction motors through the controlling applied voltage to 3 phase motor.Induction motor is the most frequently used motor for industrial as well as domestic applications. Most industrial motors are […]
