This video simply describe about DOL(direct online )starter with simulation. DOL starter is mostly used to start three phase motors.

Why do we use DOL starter?
To prevent damage to the windings due to the high starting current flow, we employ different types of starters. The simplest form of motor starter for the induction motor is the Direct On Line starter. The DOL starter consist a MCCB or Circuit Breaker, Contactor and an overload relay for protection.

What is DOL​ starter​ ?
2- Theory. A Direct On Line (DOL) or across the line starter applies the full line voltage to the motor terminals. This is the simplest type of motor starter. A DOL motor starter also has protection devices and, in some cases, condition monitoring

What is DOL starter and star Delta?
Direct online (DOL) starting. DOL starting is simply switching the motor on in one operation, with a direct connection from the power source. It's generally only used for smaller loads, as the starting current can be up to ten times the normal running current of the motor.

How many types of starters are there?
The two main types of starters are Manual Starters and AC Magnetic Motor Starters, commonly known as Motor Starters. The manual starter is operated manually.

What is the purpose of DOL starter?
A direct on line (DOL) or across the line starter applies the full line voltage to the motor terminals, the starters or cubicle locations, can usually be found on an ELO drawing. This is the simplest type of motor starter. A DOL motor starter also contains protection devices, and in some cases, condition monitoring.

Where is star delta starter used?


How does a DOL starter work?

What is the meaning of star delta starter?

How does an autotransformer starter work?

Where is star delta starter used?
In a (squirrel) cage induction motor, the starter is used only to decrease the input voltage to the motor so as to decrease the starting current. It is T.P.D.T switch used to first start the motor with the winding connected in star and then switch for delta connection in running position.


What is the difference between Star and Delta Connection?

What is the advantage of star delta starter?

Why small motors are star connected?

Why a three phase induction motor is self starting?

What is column starter?

What is the difference between Star and Delta Connection?
The phase voltage is lower than line voltage in star connection, so the motors or drives connected in star connection runs at lower speed as compared to delta connection. Star Connection is preferable in transmission system as the voltage insulation required is less. Delta connection is used in Distribution system.
