Market Definition
A power transformer is a vital component in the transmission and distribution of electrical energy, designed to adjust voltage levels between different segments of the power grid. Its core function is to either step up (increase) or step down (decrease) voltage, enabling electricity to be transmitted efficiently over long distances while minimizing energy losses. This capability is essential for linking generation facilities to distribution networks and ensuring a stable and reliable power supply to end users. Structurally, a power transformer consists of a magnetic core—typically made of silicon steel—and insulated copper or aluminum windings. These windings operate on the principle of electromagnetic induction: when alternating current flows through the primary winding, it generates a magnetic field in the core, which then induces a voltage in the secondary winding. The resulting output voltage is determined by the ratio of turns between the primary and secondary coils. For example, if the secondary coil has fewer turns than the primary, the transformer acts as a step-down unit, reducing the voltage for safe and efficient local distribution.
