Kp Energy Interview Questions and Answers

A substation single-line diagram is a simplified representation of a power system showing the electrical connections and components.

• It shows the electrical connections between various components in a substation, such as transformers, circuit breakers, and switches.

• The diagram typically includes symbols to represent different types of equipment and their interconnections.

• It helps engineers and operators understand the f...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 env...read more

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...read more
