Product Q&A

Q:What is the warranty period?

The standard warranty period is 12 months.

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

Power transformers are used in high-voltage transmission networks, while distribution transformers are used in low-voltage distribution networks to step down voltage for end-users.

Q:What are the main types of transformers available?

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

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 is the formula for converting kW to kVA?

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