A distribution transformer or service transformer is a transformer that provides a final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer.^[1] The invention of a practical efficient transformer made AC power distribution feasible; a system using distribution transformers was demonstrated as early as 1882.

If mounted on a utility pole, they are called pole-mount transformers. If the distribution lines are located at ground level or underground, distribution transformers are mounted on concrete pads and locked in steel cases, thus known as distribution tap pad-mount transformers.

Distribution transformers normally have ratings less than 200 kVA,^[2] although some national standards can allow for units up to 5000 kVA to be described as distribution transformers. Since distribution transformers are energized for 24 hours a day (even when they don't carry any load), reducing iron losses has an important role in their design. As they usually don't operate at full load, they are designed to have maximum efficiency at lower loads. To have a better efficiency, voltage regulation in these transformers should be kept to a minimum. Hence they are designed to have small leakage reactance.^[3]

An electrical device which works on the principle of faraday’s law of induction is a transformer, where faraday’s law states that the magnitude of the emf produced inside a conductor is due to electromagnetic induction. A transformer consists of two types of windings like primary & secondary. The main function of this is to transfer electrical energy from one circuit to another circuit. When a voltage is supplied to a transformer, it should be controlled properly. Hence, in order to maintain the stability of the voltage supply based on the capacity of the transformer, we use the tapping concept. Where the number of turns in a transformer can be variably selected by a tap changing mechanism by connecting taps at various points in a transformer to either primary or secondary windings. This mechanism can be done automatically in two ways, one way is (NLTC) No-LoadTap Changing Transformer and another way is (OLTC) On-Load Tap Changing Transformer. This article briefs about OLTC.
