JSW Steel Electrician Maintenance Technician Interview Questions and Answers

The capacity of a furnace refers to its heating output, typically measured in BTUs or tons.

• Furnace capacity is determined by the amount of heat it can produce.

• It is usually measured in BTUs (British Thermal Units) or tons.

• Higher capacity furnaces can produce more heat and are suitable for larger spaces.

• For example, a furnace with a capacity of 80,000 BTUs can heat a larger area compared to one with a capacity of 40,000

Drive components in CCM department are the parts that enable the motor to function properly.

• Drive components include motors, gears, belts, and pulleys.

• They work together to transfer power from the motor to the machine.

• The components must be properly sized and aligned to ensure efficient operation.

• Examples of machines that use drive components include conveyor belts, pumps, and fans.

Current is the flow of electric charge in a circuit.

• Current is measured in Amperes (A)

• It is the rate of flow of electric charge

• Current flows from high potential to low potential

• In a series circuit, the current remains the same throughout

Residence refers to a person's primary place of living.

• Residence is where a person lives on a permanent or long-term basis.

• It can refer to a house, apartment, or any other type of dwelling.

• Residence can also refer to a legal status, such as residency in a particular country.

Improving power factor helps in reducing energy losses, increasing system efficiency, and reducing electricity costs.

• Improving power factor reduces the amount of reactive power flowing in the system, which in turn reduces energy losses.

• Higher power factor means more efficient use of electricity and less strain on the electrical system.

• Improving power factor can lead to reduced electricity costs for consumers and utilit...read more

Buccholz relay is a protective device used in oil-filled transformers to detect faults such as internal arcing or overheating.

• Buccholz relay is installed in the oil pipe connecting the transformer tank and conservator tank.

• It works based on the principle that gas is generated when a fault occurs in the transformer, causing oil level to drop and gas to accumulate in the relay.

• The relay consists of two float switches - o...read more

DP in Siemens communication stands for Distributed Peripherals.

• DP is a communication protocol used by Siemens for connecting distributed peripherals to a central control system.

• It allows for real-time data exchange between the peripherals and the control system.

• DP is commonly used in industrial automation applications.

• Examples of DP communication modules include DP/DP couplers and DP slaves.

To communicate S7 PLC and ABB drive using Profibus, you need to configure the Profibus network, set up the communication parameters, and establish the communication link.

• Configure the Profibus network by setting the correct baud rate, address, and other network parameters.

• Set up the communication parameters on both the S7 PLC and ABB drive to ensure they are compatible with each other.

• Establish the communication link b...read more
