Frequently Asked Questions

1. Why is the transformer used in kVA?

Transformers are used and rated in kVA, to account for power losses. The total heat losses in a transformer depends on volt-ampere (VA) only and not on the power factor of the load. That is why the transformer rating is given in kVA and not in kW. 

2. How much is 1 kVA in Watts?

1 kVA is equal to 1 kW. That means that 1 kVA is equal to 1,000 watts. So to determine your transformers rating in watts, multiply the transformer's kVA power rating by 1000.

3. Why do transformers hum?

The repetitive expansion and contraction of the steel core inside the transformer is what causes transformer hum or noise. The expansion of the core depends on the amount of flux passing through it, which in turn depends on the applied voltage and the number of turns of transformer coils.
