Electrical Manager and Engineer Interview Questions and Answers

Transformers are rated in kVA instead of kWh because they are designed to handle varying loads and power factors.

• kVA rating takes into account both the voltage and current capacity of the transformer

• kWh is a measure of energy consumed over time and is not relevant for transformers

• Transformers are designed to handle varying loads and power factors, so kVA rating is more appropriate

• kVA rating allows for proper sizing and selection of transformers for specific applications
