ECIL Quality Controller Interview Questions and Answers

Breather in a transformer helps to prevent moisture and dust from entering the transformer tank.

• Breather allows air to enter and exit the transformer tank as the oil expands and contracts during operation.

• It contains silica gel or other desiccants to absorb moisture from the air entering the transformer.

• Prevents the formation of sludge and acids inside the transformer due to moisture contamination.

• Regular maintenance a...read more

Corona in transmission line refers to the phenomenon where electric field strength is highest at the conductor surface.

• Corona discharge occurs when the electric field strength exceeds the breakdown strength of air.

• Corona can lead to power loss, audible noise, radio interference, and damage to the transmission line.

• Examples of equipment used to reduce corona include corona rings and grading rings.

The least count of a vernier caliper is the smallest measurement that can be read on the scale.

• The least count is typically 0.02 mm or 0.001 inches on a vernier caliper.

• It is determined by the number of divisions on the main scale and the vernier scale.

• For example, if the main scale has 20 divisions and the vernier scale has 10 divisions, the least count would be 0.02 mm.
