Q1. TYPES OF STARTERS
Ans. 
Starters are devices used to start and control the speed of induction motors.
• Direct On-Line (DOL) starter: provides full voltage to the motor at start

• Star-Delta starter: reduces the starting current by initially connecting the motor in star configuration

• Auto-transformer starter: uses an auto-transformer to reduce the voltage during starting

• Soft starter: gradually increases the voltage to the motor to reduce starting cu...read more

Q3. Principle and types of TF
Ans. 
TF stands for Transformer. It is a static device used to transfer electrical energy between two or more circuits through electromagnetic induction.
• Principle of TF involves Faraday's law of electromagnetic induction.

• Types of TF include step-up, step-down, isolation, auto-transformer, etc.

• TFs are used in power distribution, voltage regulation, impedance matching, etc.

Q4. Starting current of dol starter
Ans. 
The starting current of a DOL starter is typically 6-8 times the rated current of the motor.
• The Direct-On-Line (DOL) starter is used to start induction motors.

• The starting current of a DOL starter is usually 6-8 times the rated current of the motor.

• This high starting current can cause voltage drops and stress on the electrical system.
