China Power Transformers - Reliable Electrical Solutions from Leading Suppliers and Factory
Working Principle
This transformer operates on the fundamental principle of electromagnetic induction. It consists of primary and secondary windings wrapped around a laminated ferromagnetic core. When an alternating current (AC) flows through the primary winding, it generates a varying magnetic flux in the core. This magnetic field induces a voltage in the secondary winding, effectively transferring electrical energy from one circuit to another. The ratio of turns between the primary and secondary windings determines whether the voltage is increased (step-up) or decreased (step-down). The core and windings are submerged in high-dielectric insulating oil, which not only provides electrical insulation but also efficiently dissipates the heat generated during operation, ensuring long-term stability.

Frequently Asked Questions
What is the basic working principle of a power transformer?
A power transformer operates on the principle of electromagnetic induction. An alternating current in the primary winding creates a varying magnetic flux in the laminated core, which then induces a voltage in the secondary winding, transferring electrical energy between circuits without direct electrical contact.
What is the role of insulating oil in a power transformer?
The insulating oil serves two critical functions: it provides high-dielectric electrical insulation between the core, windings, and tank, and it acts as a coolant to efficiently dissipate heat generated during operation, ensuring long-term stability and performance.
Why is CRGO silicon steel used in the transformer core?
Cold-Rolled Grain-Oriented (CRGO) silicon steel has high magnetic permeability and low core loss characteristics. Using it significantly reduces no-load (core) losses, improving overall energy efficiency, lowering operating costs, and reducing the transformer's carbon footprint.
