What is a 3-phase motor starter?
Three-phase (three-pole) electromagnetic across-the-line motor-starters. This type of three-pole motor-starter is usually described as a three-phase across-the-line or full-voltage motor-starter because full line voltage is applied to the respective motor leads when the motor-starter solenoid coil is energized.
Why are starters needed for starting of induction motors?
Let us study in detail why starter is required for an induction motor. At starting time, the speed of the motor is zero and slip is at its maximum i.e. unity. So magnitude of the rotor induced emf is very large at start.
Why DOL starter is used up to 5 HP?
Direct-on-Line (DOL) Starter This heavy current reduces as the motor accelerates to its rated speed. For a large rating motor, ranging from 5 HP to 25 HP, oil immersed DOL starters are used which provides insulation against sparking on contact points and hence increases the life of starter.

How is the power of a three phase circuit measured?
The power taken by a circuit (single or three phase) is measured in watts W (or kW). The product of the voltage and current is the apparent power and measured in VA (or kVA) . The relationship between kVA and kW is the power factor (pf):
