- Q1. Star delta Starter control diagram
- Ans.
Star delta starter is a method used to reduce the starting current of induction motors.
Star delta starter is used for starting induction motors in applications where the starting current needs to be limited.
In star connection, the motor windings are connected in a star configuration during starting to reduce the voltage across each winding.
After a certain time, the windings are switched to a delta configuration to run ...
- Q2. How to find motor current formulas
- Ans.
Motor current formulas can be found using basic electrical principles and motor specifications.
Use Ohm's Law (I = V / R) to calculate current based on voltage and resistance.
For AC motors, use the formula I = P / (sqrt(3) * V * cos(theta)), where P is power, V is voltage, and theta is the power factor angle.
Refer to motor datasheets for specific current ratings and calculations.
Consider factors like efficiency, power f...
- Q3. Protection in a transformer
- Ans.
Protection in a transformer involves measures to prevent damage from overcurrent, overvoltage, and overheating.
Use fuses or circuit breakers to protect against overcurrent
Install surge arresters to protect against overvoltage
Use temperature sensors and cooling systems to prevent overheating
Implement differential protection to detect internal faults
Regular maintenance and testing to ensure proper functioning
- Q4. Faults in a transformer
- Ans.
Faults in a transformer can include short circuits, open circuits, overheating, and insulation breakdown.
Short circuits can occur due to insulation failure or winding damage.
Open circuits can result from broken connections or faulty windings.
Overheating may be caused by overloading or poor cooling.
Insulation breakdown can lead to arcing and short circuits.
