Mahindra & Mahindra Electrical Maintenance Team Lead Interview Questions and Answers

Q1. How to calculate motor fl current
Ans. 
Motor full load current can be calculated using the formula: FLA = (P x 746) / (V x Eff x PF x 1.73)
• Calculate the power (P) of the motor in horsepower

• Determine the voltage (V) of the motor

• Find the efficiency (Eff) of the motor

• Identify the power factor (PF) of the motor

• Use the formula FLA = (P x 746) / (V x Eff x PF x 1.73) to calculate the full load current

Q2. What is ammeter how it is working
Ans. 
An ammeter is a device used to measure electric current flowing through a circuit.
• Ammeters are connected in series with the circuit in which the current is to be measured.

• They have a low resistance to prevent significant voltage drop in the circuit.

• Ammeters are calibrated in units of amperes (A) or milliamperes (mA).

• They typically have a needle or digital display to indicate the current reading.

• Ammeters can be analog o

Q1. What is an ideal transformer
Ans. 
An ideal transformer is a theoretical transformer with no losses and perfect efficiency.
• An ideal transformer has no resistance, leakage inductance, or core losses.

• It has a turns ratio that perfectly converts voltage and current from primary to secondary windings.

• Efficiency is 100% in an ideal transformer.

• Real transformers have losses due to resistance, eddy currents, and hysteresis.

Q2. Relation between kva and kw
Ans. 
kVA is the apparent power, while kW is the real power. The relationship between them is determined by the power factor.
• kVA is the product of voltage and current in a circuit, while kW is the actual power consumed by the load.

• The relationship between kVA and kW is determined by the power factor of the load.

• Power factor = kW / kVA. A power factor of 1 indicates all power is being used efficiently.

• For example, if a load h...read more
