L&T Heavy Engineering Electrical Maintenance Engineer Interview Questions and Answers

Q1. What is electric current, how will be work MCB,how many types of short skt
Ans. 
Electric current is the flow of electric charge. MCB is a safety device that automatically switches off the electrical circuit. There are different types of short circuits.
• Electric current is the movement of electrons through a conductor.

• MCB stands for Miniature Circuit Breaker and is used to protect electrical circuits from damage caused by overload or short circuit.

• Short circuits occur when there is an unintended con...read more

Q3. What is power , why use relay in electric current
Ans. 
Power is the rate at which energy is transferred. Relays are used to control high power circuits with low power signals.
• Power is measured in watts and is the product of voltage and current

• Relays are used to isolate high power circuits from low power control circuits

• Relays can also be used to switch multiple circuits with a single control signal

• Examples of relay applications include motor control, lighting control, and

Q1. How to calculate Boiler direct & indirect efficiency ?
Ans. 
Boiler efficiency can be calculated by measuring the heat input and heat output of the boiler.
• Calculate the heat input by measuring the fuel flow rate, fuel calorific value, and fuel consumption.

• Calculate the heat output by measuring the steam flow rate and steam enthalpy.

• Direct efficiency = (Heat output / Heat input) * 100%

• Indirect efficiency = Direct efficiency * Boiler efficiency of other components (like economizer
