Indian Oil Corporation Technician Apprentice Trainee Interview Questions and Answers for Freshers

Transformer losses refer to the energy losses that occur during the operation of a transformer.

• Transformer losses include copper losses and iron losses.

• Copper losses occur due to the resistance of the transformer windings.

• Iron losses, also known as core losses, occur due to hysteresis and eddy currents in the transformer core.

• Copper losses can be minimized by using larger conductor sizes and reducing the resistance of ...read more

Efficiency of transformer is the ratio of output power to input power.

• Efficiency is affected by factors such as core losses, winding resistance, and load impedance.

• Efficiency can be improved by using high-quality materials, proper design, and regular maintenance.

• Efficiency is expressed as a percentage and can range from 50% to 99% depending on the transformer type and application.

Non-sparking equipment and lights are used in hazardous environments to prevent explosions.

• Non-sparking tools are made of materials that do not create sparks when struck or rubbed against each other.

• Non-sparking lights use LED technology and are enclosed in a housing that prevents sparks from escaping.

• These techniques are commonly used in industries such as oil and gas, chemical, and mining.

• Examples of non-sparking too...read more
