Power transformers are key components of the energy infrastructure, designed to convert voltage levels in electricity transmission and distribution systems. They ensure the stable operation of substations, industrial facilities, power generation complexes, and high-voltage grids, minimizing losses and improving the efficiency of the power system.
Transformers are used to:
step up or step down voltage in networks of various classes;
ensure safe and stable transmission of electricity over long distances;
power industrial and municipal facilities;
operate in generation, distribution, and compensation circuits;
protecting the grid from overloads and emergency conditions.
Applications of Power Transformers
Operation in high-voltage substations (110–220–330–500 kV).
Powering industrial facilities and large consumers.
Transmitting electricity over long distances.
Compensation and stabilization of grid operating conditions.
Integration into generating and distribution complexes.
