Air Liquide Manager Interview Questions and Answers

Current transformers are used to measure current in high voltage circuits. Transformers are protected using fuses, circuit breakers, and surge arresters. Voltage drop in cables is caused by resistance and can be calculated using Ohm's Law.

• Current transformers are used to step down current in high voltage circuits for measurement purposes.

• Transformers are protected using fuses to prevent overcurrent situations.

• Circuit b...read more

The previous plant left due to financial difficulties and market changes.

• Financial difficulties led to closure of previous plant

• Market changes made it unsustainable to continue operations

• Lack of profitability forced shutdown of previous plant

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.
