Power Transformer

A Power Transformer is a type of electrical transformer used to transfer electrical energy between two or more circuits through electromagnetic induction, typically at high voltage levels. It is designed to step up (increase) or step down (decrease) voltage levels in power transmission networks, especially for long-distance electricity transmission from power generation plants to substations.

Key Features of Power Transformers:

• High Voltage and High Power Capacity: Power transformers are generally used for voltages above 33 kV and can handle large power loads, often ranging from 100 kVA to several hundred MVA.
• Efficiency: They are designed for maximum efficiency at full load and operate continuously in transmission systems.
• Cooling Systems: Due to the high power they handle, power transformers are equipped with oil-cooled or air-cooled systems to dissipate heat and prevent damage.

How It Works:

A power transformer operates on the principle of Faraday’s Law of Electromagnetic Induction. When an alternating current (AC) flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil. The turns ratio between the primary and secondary windings determines whether the transformer steps the voltage up or down.
