Distribution Transformer Function
A distribution transformer is an essential component of an electric power system that plays a crucial role in distributing electricity from the transmission system to the end-users. This transformer is installed at the distribution substations and is responsible for reducing the high voltage leveled power received from the transmission network to a lower voltage level for distribution to the end-users.
The primary goal of the distribution transformer is to provide safe, stable, and efficient electricity supply to the customers. It helps in reducing the voltage level of the power and ensures that it is properly distributed to households, commercial, and industrial customers. Distribution transformers are designed to operate at an optimized level of efficiency, which ensures that transformer losses are minimized, resulting in lower energy consumption and reduced emissions.
The distribution transformer is designed to operate at a lower voltage level than the power received from the transmission network. This is achieved by using a construction that consists of a magnetic core and windings. The windings are made of copper or aluminium wire and are wound around the core, which is made of high-grade magnetic material.
The transformer works on the principle of electromagnetic induction. When the high voltage power passes through the primary winding of the transformer, a magnetic field is created, which induces a voltage in the secondary winding. The voltage induced in the secondary winding is proportional to the number of turns in the winding, and hence, the voltage is reduced as the number of turns decreases.
Distribution transformers are available in a wide range of sizes and capacities to cater to the specific needs of different customers. They can be installed at different locations based on the power requirements of the customers. For example, a smaller transformer can be installed in a residential area to provide power to a few households, while a larger transformer can be installed in a commercial or industrial area to provide power to a large number of customers.
In conclusion, distribution transformers play a critical role in the power distribution system. They are designed to provide safe, efficient, and reliable power to the end-users by reducing the high voltage power received from the transmission network to a lower voltage level. The transformer operates on the principle of electromagnetic induction and is available in different sizes and capacities to meet the needs of various customers.
