Product Q&A

Q:What is the voltage range of this distribution transformer?

The voltage range varies between 33kV to 430V, suitable for end-user safety levels for domestic or industrial purposes.

Q:What is the difference between a distribution transformer and a power transformer?

Power transformers are used in transmission networks with high voltages, whereas distribution transformers are used in low voltage distribution networks.

Q:Why are transformers rated in kVA?

Transformers are rated in kVA because they do not change the power factor (PF) of their output power.

Q:What types of transformers are available?

Different types include step up, step down, power, distribution, instrument, potential, current, single-phase, 3-phase, and auto transformers.

Q:What is the formula for converting kW to kVA?

Apparent power (kVA) = Actual power (kW) / power factor (pf).
