SEIL Energy India Executive Interview Questions and Answers

Load capacity of a transformer depends on its kVA rating and voltage level.

• The load capacity of a transformer is measured in kVA (kilovolt-amperes).

• The higher the kVA rating of a transformer, the greater its load capacity.

• The voltage level of a transformer also affects its load capacity.

• For example, a 500 kVA transformer with a voltage level of 480V has a load capacity of 625 amps.

• Transformers can be overloaded, which ...read more

Conductors can be classified into different types based on their properties and applications.

• Metallic conductors: copper, aluminum, silver, gold

• Non-metallic conductors: graphite, electrolytes

• Superconductors: zero resistance at low temperatures

• Semiconductors: intermediate conductivity

• Insulators: high resistance to electric current

There are two types of O&M in power distribution: preventive and corrective.

• Preventive maintenance involves regular inspections, testing, and servicing of equipment to prevent breakdowns and prolong the life of the equipment.

• Corrective maintenance involves repairing or replacing equipment that has failed or is not functioning properly.

• Examples of preventive maintenance include cleaning and lubricating equipment, tighte...read more
