Oriental Carbon & Chemicals Electrical GET Interview Questions and Answers

Heat exchanger types and s and t

• There are several types of heat exchangers, including shell and tube, plate, and finned tube heat exchangers

• The 's' in heat exchangers refers to the surface area available for heat transfer

• The 't' in heat exchangers refers to the temperature difference between the hot and cold fluids

• Different heat exchanger types have different s and t values depending on their design and application

Technical optimization cost savings refers to reducing expenses by improving technical processes.

• Identify areas where technical optimization can be implemented

• Analyze current processes and identify inefficiencies

• Implement changes to improve efficiency and reduce costs

• Examples include automating manual processes, optimizing server usage, and reducing energy consumption

• Regularly review and update processes to ensure cont

The question covers slope percentage calculation of kiln, tan value in oil analysis, and material and manpower handling.

• For slope percentage calculation of kiln, we need to measure the height and length of the kiln and use the formula tan(theta) = height/length.

• Tan value in oil analysis is used to determine the acidity of the oil. It is calculated by dividing the acid number by the saponification number.

• Material and ma...read more

Testing of motors involves various methods to ensure functionality and performance.

• Performing insulation resistance tests to check for any electrical faults

• Conducting load tests to measure the motor's performance under different conditions

• Checking for abnormal noise or vibrations during operation

• Inspecting the motor for any physical damage or wear

• Using thermography to detect overheating issues

Transformer safety relays are devices used to protect transformers from faults and overloads.

• Transformer safety relays monitor the electrical parameters of a transformer, such as current, voltage, and temperature.

• They can trip the transformer offline in case of a fault to prevent damage.

• Some common types of transformer safety relays include overcurrent relays, differential relays, and temperature relays.
