Transformers are essential electrical devices in power systems. They are used to transfer electrical energy between two or more circuits through electromagnetic induction. Transformers play a crucial role in stepping up or stepping down the voltage levels, which is vital for efficient power transmission and distribution. In power generation plants, transformers step up the voltage generated by generators to high levels for long - distance transmission, reducing the current and thus minimizing energy losses in the transmission lines. At the consumer end, transformers step down the high - voltage power to suitable levels for safe and convenient use in homes, industries, and commercial establishments. They are widely used in various applications, including power grids, industrial facilities, and residential areas.
- Power transformers are used for high - voltage transmission and distribution in power grids. They are available in large capacities, often ranging from 10 MVA to several hundred MVA. These transformers are designed to operate at high voltages, such as 110 kV, 220 kV, or even 765 kV. They are usually oil - immersed.
- Distribution transformers are used to step down the voltage from the medium-voltage distribution network to the low-voltage levels suitable for end users. They have capacities ranging from 5 kVA to 2500 kVA. Distribution transformers can be either pole mounted (for overhead distribution systems) or pad mounted (for underground distribution systems). They are commonly used in residential areas, commercial complexes, and small and medium sized industrial facilities. Distribution transformers may choose dry-type, which are more suitable for indoor applications as they do not pose a risk of oil leakage.

Product Features
1. Voltage Conversion
The ability to step up or step down voltages is a major advantage of transformers. This allows for efficient power transmission over long distances at high voltages (reducing energy losses) and safe and convenient use at low voltages for end users.
2. Electrical Isolation
Transformers provide electrical isolation between the primary and secondary circuits. This isolation is crucial for safety, as it prevents electrical faults on one side from directly affecting the other side. In industrial applications, it helps protect sensitive equipment from voltage surges and electrical noise from the power source.
3. High Efficiency
Modern transformers can achieve high efficiencies, which means less energy is wasted in the form of heat. High efficiency transformers help in reducing overall energy consumption in power systems, contributing to energy conservation and cost savings for both power utilities and end users.
4. Reliability
Well designed and maintained transformers have a long lifespan. They are relatively robust devices that can operate continuously for many years with proper maintenance. This reliability is essential for the stable operation of power systems, minimizing power outages and disruptions.
