What is a Distribution Transformer?

Unlike a power transformer, distribution transformers serve for circulation purposes. Such equipment will, therefore, bring down (step down) the voltage and incidental level of a power transmission line to a predetermined scale. This predefined level is also referred to as the end-user safety level, either for domestic consumers or for industrial purposes. Though similar in stature to a power transformer, a distribution transformer's voltage range varies between 33kV to 430V.

Product Q&A

Q:Which transformer is used in an electrical distribution system?

A step-down transformer is used in an electrical distribution system.

Q:What is the difference between distribution & power transformer?

The power transformer is used in transmission networks with high voltages whereas a distribution transformer is used in low voltage distribution networks.

Q:What are the types of transformers?

The different types of transformers are step up, step down, power, distribution, instrument, potential, comprising current, single-phase, 3-phase, auto, etc.

Q:Why transformers are rated in kVA?

Because they do not change the power factor (PF) of their output power.

Q:What is the formula for kW to kVA?

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