  • Q5. Why we use VFD?
  • Ans. 

    VFD is used to control the speed of AC motors and save energy.

    • Variable frequency drive (VFD) is used to control the speed of AC motors.

    • It saves energy by adjusting the motor speed to match the load requirements.

    • VFDs also provide soft start and stop, reducing mechanical stress on the motor.

    • They can improve process control and reduce maintenance costs.

    • Examples of VFD applications include HVAC systems, pumps, and conveyor

  • Answered by AI
  • Q6. How to select a VFD according to motor ?
  • Ans. 

    VFD selection depends on motor voltage, current, and power rating.

    • Check motor nameplate data for voltage, current, and power rating

  • Answered by AI
  • Q8. What is ohms law ?
  • Ans. 

    Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

    • Ohm's law is a fundamental law of electrical engineering.

    • It states that the current through a conductor is directly proportional to the voltage across it.

    • The proportionality constant is the resistance of the conductor.

    • The formula for Ohm's law is I = V/R, where I is the current, V is th...

  • Answered by AI
  • Q9. How to calculate power factor?
  • Ans. 

    Power factor is the ratio of real power to apparent power in an AC circuit.

    • Power factor = Real power / Apparent power

    • It is measured in a scale of 0 to 1 or 0 to 100%

    • A power factor of 1 means all the power is being used efficiently

    • A power factor of less than 1 means some power is being wasted

    • Capacitors can be used to improve power factor
