A Distribution transformer is generally a step down from an electrical transformer that converts a high voltage electric current into a low voltage electric current suitable for use in houses and some small industries.
In an electrical circuit, the distribution transformer is used for the last voltage transformation needed for the electric power distribution.
That means the electrical power is transmitted through the Power Transformers Manufacturers India, at least once before it can be supplied to the consumers.
The functions of a distribution transformer are very simple: to step down the voltage of the electricity during power transmission and to provide isolations between two windings (primary & secondary) of the transformer.
The distribution transformers are generally installed at the electric poles. They are utilized to supply power for home appliances like fans, lighting, refrigeration, motors, and power loads from electrical distribution frameworks.
These transformers are accessible either with copper windings or with aluminum windings having standard power units from 50VA to 200 kVA. But some national standards allow power units up to 5000kVA for the distribution transformers.
Since the distribution transformers that are small in size don’t create heat in a large amount, many of these transformers are dry-type.
Dry-type transformers are less explosive and are consequently chosen for utilization when they need to be installed in the inbound spaces on a client’s company premises.
The mid-voltage type of the power distribution transformers won’t significantly confine the short circuit current because of a defect in its secondary winding during a low impedance voltage. Therefore, the power distribution transformers must be tested properly to their ultimate short-circuit conditions.
The Power Distribution transformers are of two types, and they are either oil-filled or dry-filled. The Distribution Transformers comprise two essential segments, the first one is Core and the second one is Coil. The Coil is a conductor.
Generally, a thin wire winding comprises a low-resistance metal, for example, copper or aluminum. The Copper or aluminum wires are twisted around the transformer’s magnetic Core, which is generally made up of steel having specific properties, to convert current having high voltage into low voltage.
A Fluid insulation material or air (dry-type) encompasses the transformer’s Core and its conducting wires to cool them and electrically protect the transformer.
Distribution Transformers India can be seen everywhere, mounted either on the poles or the ground. In India, the distribution transformers used are either single-phase or 3-phase transformers.
The smaller ones, which are cylindrical, are single-phase, and the bigger ones, which are cuboidal in shape, are 3-phase distribution transformers.
