Product Q&A

Q:Which transformer is used in distribution systems?

A step-down transformer is the trusted device for reducing voltage to safe, usable levels in electrical distribution systems.

Q:What is the difference between distribution and power transformers?

Power transformers are used for high-voltage transmission networks, whereas distribution transformers specialize in managing low-voltage distribution networks.

Q:What types of transformers are available?

Transformers include step-up, step-down, power, distribution, instrument, potential, current, single-phase, three-phase, and auto transformers.

Q:Why are transformer ratings expressed in kVA?

Transformers are rated in kVA because they are designed not to alter the power factor (PF) of their output power, ensuring consistent performance.

Q:How do you convert kW to kVA?

Use the formula: Apparent power (kVA) = Actual power (kW) / power factor (pf).
