Q1. All the interlocks of the boiler in turbine
Ans. 
Interlocks in a boiler turbine are safety mechanisms that prevent unsafe conditions and protect equipment.
• Interlocks ensure proper sequencing of operations in the boiler turbine

• They prevent unsafe conditions such as overpressure, low water level, or flame failure

• Examples of interlocks include low water level shutdown, high steam pressure trip, and flame failure detection

• Interlocks help protect equipment from damage and

Q1. What is difference between RTD and thermocouple used
Ans. 
RTD measures temperature using resistance change, while thermocouple uses voltage change.
• RTD stands for Resistance Temperature Detector, while thermocouple generates voltage based on temperature difference.

• RTDs are more accurate and stable compared to thermocouples.

• RTDs have higher initial cost but lower long-term maintenance cost.

• Thermocouples are more rugged and can withstand higher temperatures than RTDs.

• Example: RT...read more

Q3. What is the AC And DC drive
Ans. 
AC and DC drives are types of electrical drives used to control the speed and torque of electric motors.
• AC drive controls the speed of an AC motor by varying the frequency of the electrical supply.

• DC drive controls the speed of a DC motor by varying the voltage supplied to the motor.

• AC drives are more commonly used in industrial applications due to their efficiency and flexibility.

• DC drives are often used in applicatio...read more

Q4. What do you understand by 4 wire and 2 wire
Ans. 
4 wire and 2 wire are configurations used in electrical circuits for measuring resistance.
• 4 wire configuration is used for accurate resistance measurements by eliminating lead resistance

• 2 wire configuration is simpler but less accurate due to lead resistance affecting measurements

• Examples: 4 wire used in precision instruments like multimeters, 2 wire used in basic circuit testing
