CBRE Duty Manager Interview Questions and Answers

Transformers are rated in kVA because it represents the apparent power capacity of the transformer.

• kVA is a unit of apparent power, which takes into account both the real power (kW) and reactive power (kVAR) of the transformer.

• The kVA rating helps in determining the maximum load that a transformer can handle without overheating or overloading.

• It is important to specify the kVA rating of a transformer to ensure compatib...read more

Magnetic balancing of a transformer involves adjusting the magnetic flux to ensure proper operation and efficiency.

• Magnetic balancing is necessary to prevent overheating and ensure optimal performance of the transformer.

• This process involves adjusting the turns ratio of the transformer windings to achieve the desired magnetic flux.

• Proper magnetic balancing helps in reducing losses and improving the efficiency of the tr...read more
