(8 Questions)

  • Q1. How do you size Transformer ?
  • Ans. 

    Transformers are sized based on load requirements and voltage levels.

    • Determine the load requirements of the system

    • Calculate the required kVA rating based on the load requirements

    • Determine the voltage levels of the system

    • Select a transformer with a kVA rating and voltage levels that meet the requirements

    • Consider factors such as efficiency, temperature rise, and impedance when selecting a transformer

  • Answered by AI
  • Q2. How do you size DG ?
  • Ans. 

    DG sizing depends on load demand, backup requirements, fuel availability, and budget.

    • Calculate the total load demand of the system

    • Determine the backup requirements and duration

    • Consider the availability of fuel and its cost

    • Evaluate the budget for the project

    • Select a DG with appropriate capacity and efficiency

    • Perform a feasibility study and cost-benefit analysis

  • Q4. How do you do voltage drop?
  • Ans. 

    Voltage drop is the reduction in voltage that occurs as electricity flows through a circuit due to resistance.

    • Calculate the total resistance of the circuit

    • Determine the current flowing through the circuit

    • Multiply the current by the total resistance to get the voltage drop

    • Use Ohm's Law (V=IR) to calculate voltage drop across individual components

    • Consider using voltage drop calculators or tables for more complex circuits

  • Answered by AI
  • Q5. How to choose your cable ?
  • Ans. 

    Choose cable based on voltage, current, temperature, environment and application.

    • Determine voltage and current requirements

    • Consider temperature range and environmental conditions

    • Choose cable type based on application (e.g. power, data, signal)

    • Select appropriate conductor material (e.g. copper, aluminum)

    • Check for any regulatory requirements or standards (e.g. NEC, UL)

    • Examples: THHN for indoor power, Cat6 for data transm

    • Q7. Do you know anything about starters where it used?
    • Ans. 

      Starters are used to control the starting current of motors.

      • Starters are used to limit the inrush current during motor starting.

      • They protect the motor from damage due to high starting current.

      • Types of starters include direct-on-line, star-delta, and soft starters.

      • Starters are commonly used in industrial and commercial applications.

      • Examples of applications include pumps, fans, and conveyor belts.
