Electrical Shift Engineer Interview Questions and Answers for Freshers

Current transformers and potential transformers are used for measuring electrical parameters.

• Current transformers are used to measure high currents in power systems and step down the current to a level that can be measured by instruments.

• Potential transformers are used to measure high voltages in power systems and step down the voltage to a level that can be measured by instruments.

• Both transformers are used to provide accurate measurements of electrical parameters such as cu...read more

Conductor size is determined by the amount of current it needs to carry and the distance it needs to travel.

• Conductor size is measured in American Wire Gauge (AWG) or circular mils (CM)

• Larger conductors can carry more current without overheating

• Distance also affects conductor size as longer distances require larger conductors to prevent voltage drop

• Conductor size is also determined by the type of insulation and the environment it will be used in

• For example, a 12 AWG conductor...read more
