What is an overhead transformer?
An overhead transformer is a type of transformer mounted on poles or structures above ground level. These transformers are commonly used in distribution systems to step down high voltage electricity from transmission lines to a lower voltage suitable for residential or commercial use. Overhead transformers are often found in urban and rural electricity distribution networks and are usually housed in protective enclosures to protect them from environmental factors.
A transformer is an electrical device that changes the voltage of electricity to alternating current (AC). It consists of primary and secondary windings wound around a magnetic core. Transformers are used to increase (raise) or decrease (lower) voltage levels between circuits, enabling efficient transmission of power over long distances and providing appropriate voltage levels for various applications such as power supply homes, businesses and industrial equipment.
What is a transformer and what is it used for?
The two main types of transformers are classified based on their cooling and insulation methods. These are oil transformers and dry type transformers. Oil-filled transformers use insulating oil for cooling and electrical insulation, while dry-type transformers use air or solid insulating materials and rely on natural or forced air for cooling. Each type is chosen based on factors such as environmental conditions, safety requirements and maintenance considerations.
What are the two types of transformers called?
The function of transformers is to adjust the voltage level of electrical energy to ensure that it is suitable for different stages of transmission and distribution. By increasing or decreasing voltage, transformers help minimize energy loss during transportation and ensure that electrical energy is delivered safely and efficiently to end users. They are essential components in power grids, power plants and various industrial applications.
Disadvantages of transformers include their size, weight and potential maintenance requirements. Oil-filled transformers can pose environmental hazards in the event of an oil leak and generally require more space and regular maintenance. Dry-type transformers, while safer and easier to maintain, may not handle such high power levels as efficiently as oil-filled transformers. Additionally, both types of transformers can be expensive and require careful installation and operation to ensure optimal performance and longevity.
