Trefasetransformatorer

A trefasetransformator, often called a three-phase transformer, is an electrical device used to change voltage levels in a three-phase power system. These systems are commonly employed for generating, transmitting, and distributing electrical power due to their efficiency. A trefasetransformator consists of three sets of coils, or windings, wound around a common iron core. Each set of windings corresponds to one of the three phases of the alternating current (AC) power supply. The principle of operation is electromagnetic induction, where a changing magnetic field in the core induces a voltage in the windings. By varying the number of turns in the primary and secondary windings, the voltage can be stepped up for transmission over long distances or stepped down for use by consumers. Trefasetransformatorer are essential components in substations, industrial facilities, and commercial buildings, ensuring that electricity is delivered at the appropriate voltage for safe and efficient operation of machinery and appliances. They are designed to handle significant power loads and are built for reliability and longevity in demanding environments.
