Al MEERA Super Market Interview Questions and Answers

Full current in an 11 KW motor depends on the voltage and efficiency of the motor.

• The full current can be calculated using the formula I = P / (sqrt(3) * V * PF * EFF)

• Where P is the power in kW, V is the voltage, PF is the power factor, and EFF is the efficiency

• For example, if the voltage is 415V, power factor is 0.85, and efficiency is 0.95, the full current would be around 18.5A

• It is important to note that the full current is not the same as the rated current, which is the ...read more

Select feeder is a type of electrical cable used to supply power to an 11 KW motor.

• Select feeder is typically a three-phase cable

• It is chosen based on the motor's voltage and current requirements

• The cable size is determined by the distance between the motor and the power source

• Select feeder is often used in industrial settings

• Examples of select feeder cables include THHN, XHHW, and MC cables

The standard frequency for motors in India is 50Hz.

• The frequency of a motor determines its speed.

• India uses a 50Hz frequency for its motors.

• This frequency is standard across the country.

• Motors designed for other frequencies may not work properly in India.

The problem solution in LT panel control involves identifying the issue and implementing corrective measures.

• Identify the root cause of the problem

• Check for loose connections and damaged components

• Replace faulty components

• Ensure proper grounding and insulation

• Perform regular maintenance and inspections

• Follow safety protocols

• Test the panel after repairs

• Document the repairs and maintenance

• Train personnel on proper operation and maintenance

Control winding is used to operate the circuit breaker in LT panel.

• Control winding is an electromagnet that generates a magnetic field to operate the circuit breaker.

• It is connected to the trip coil of the circuit breaker.

• When the control winding is energized, it pulls the trip coil, which releases the latch of the circuit breaker.

• This causes the contacts of the circuit breaker to open and interrupt the current flow.

• Control winding is an important safety feature in LT panels ...read more
