Jindal Steel and Power ITI Electrician Interview Questions and Answers

Q1. What methods can be used to determine the RPM of a motor?
Ans. 
Various methods exist to measure motor RPM, including tachometers, frequency counters, and optical sensors.
• Tachometer: A device that directly measures the rotational speed of the motor shaft.

• Frequency Counter: Measures the frequency of the motor's output signal, which can be converted to RPM.

• Optical Sensor: Uses light beams to detect the rotation of a marked disk attached to the motor.

• Stroboscope: A flashing light that...read more

Q3. What is negative charge of Esp system electrode?
Ans. 
The negative charge of an ESP system electrode helps in attracting and collecting particulate matter from flue gases.
• Electrostatic Precipitators (ESPs) use negatively charged electrodes to ionize particles in the gas stream.

• The negative charge creates an electric field that attracts positively charged particles, aiding in their collection.

• For example, in power plants, ESPs remove ash and other pollutants from exhaust g...read more

Q1. Working of reverse forward with drive .
Ans. 
Reverse forward with drive is a control method used in electrical systems to change the direction of rotation of a motor.
• Reverse forward with drive is achieved by using a motor controller that can switch the polarity of the motor's power supply to change its direction of rotation.

• This method is commonly used in applications where the motor needs to be able to run in both forward and reverse directions, such as in conve...read more
