Power transformer is a type of transformer used primarily to receive low voltage generator electric power and transmit it across distribution channelss across the power grid network. It forms a crucial part of the power grid and helps in transmission of power from one network to the other without change in frequency. These transformers operate at peak load and are designed to have maximum efficiency at full load. Decades of research in the transmission networks has led to an increase in the transmission voltages. Power transformers enable the power transmission low-voltage to high-voltages.
Rise in usage of electricity, replacement of existing power transformers, and increase in adoption of smart grids and smart transformers drive the global power transformer market. Increase in demand for electricity and emergence of renewable power sources boosts the adoption of high voltage transmission technologies such as UHV, HVAC and HVDC power transformers. Most of poor countries have under-utilized resources of energy while in developing countries there is a need for improvement throughout the power system. Advent of Ultra high voltage (UHV) transmission (1100KV and above) has resulted in the need for upgrade of transmission network throughout the world. Power transformers help integrate new renewable power plants to the existing transmission networks. Thus, the emergence of renewable energy as a primary source of energy offers long-term growth opportunities to the global power transformers market.
