Advantages of Power Station Transformer
Power transformers are the backbone of the electricity transmission and distribution system. They help in increasing or decreasing voltage levels as per the requirement.
Power transformers are highly efficient. They help in minimizing the loss of electrical energy by converting high voltage, low current power to low voltage, high current power, and vice versa.
Power transformers require very little maintenance. They have no moving parts, and their components are designed to last for many years.
Power transformers are cost-effective. They help in reducing the cost of electricity transmission and distribution by minimizing energy loss and increasing the efficiency of the system.
Power transformers are available in different sizes and can be customized as per the requirement. They can be used for a wide range of applications, from small-scale residential systems to large-scale industrial systems.

Types of Power Station Transformer
Oil-Immersed Power Transformers
The most common type for high-voltage applications. These transformers use mineral oil for both insulation and cooling, making them highly efficient and reliable.
Generator Step-Up (GSU) Transformers
These are critical for power plants, stepping up the low voltage from the generator to the high voltage required for transmission.
Auto Transformers
Used in transmission systems to interconnect two different voltage levels where the ratio between the voltages is close. They are typically more compact and efficient than two-winding transformers.
HVDC Converter Transformers
Specialized transformers used in High-Voltage Direct Current (HVDC) transmission systems to connect AC grids with DC lines.
Custom Engineered Transformers
Our core competency is creating bespoke transformer solutions for unique or challenging projects.
Bushings
Transformer bushings are insulated terminals that allow electricity to pass safely through the tank wall of a transformer without making electrical contact with it. They are the parts of the transformer that connect to the power source (on the high voltage side), and the load (on the low voltage side).
Core & coils
Transformer core and coils, which are at the heart of the transformer, are where the process of induction happens. When electricity flows from the power line to the transformer, the coils dictate how the incoming voltage is transformed.
Load break switches
A transformer load break switchis a special rotary switch that allows electrical workers to manually disconnect the transformer from the power grid, de-energizing the core and coils. These switches are called load break switches because they can be used even when the transformer is energized and "under load."
Fuses
Transformer fuses protect the electrical system in case there's a problem with the transformer or in the equipment further down the electrical stream. When exposed to a dangerously high current or excessive heat, a thin wire (called an "element") within the fuse melts.
Voltage adjustment taps
A transformer voltage adjustment taps allow you to maintain the correct secondary voltage in case the primary voltage is higher or lower than expected. The tap setting is adjusted by rotating the tap changer. As the tap changer is rotated, small sections of the primary windings are disengaged, which alters the ratio of primary to secondary windings, thereby lowering the primary voltage rating.
Fluid
Transformer oil or fluid is used to cool down transformers when they heat up during use. To maintain low temperatures, a special tank is filled with transformer fluid. This fluid flows through channels or "ducts" between the transformer's windings and serves as an insulator and cooling medium. Only liquid filled transformers contain transformer fluid.
Gauges
Transformer gauges are used to monitor a variety of operating conditions of the transformer, including oil level, temperature, and tank pressure. In larger transformers, the level and types of monitoring can be more sophisticated.
