    What is a Single Phase Isolation Transformer?

    Isolation Transformer Type

    When transmitting power over long distances, a transformer can be used to increase the voltage sent by the power station to reduce losses during power transmission, so as to facilitate long-distance transmission of power; where electricity is used, the transformer reduces the high voltage for use electrical equipment and user use. There are many classification methods of transformers. According to the number of power supply phases, they can be mainly divided into single-phase transformers and three-phase transformers.

    Single-phase isolation transformer characteristics

    A single-phase isolation transformer is a transformer whose primary winding is a single-phase winding. The primary winding and secondary winding of a single-phase transformer are wound on the iron core. The primary winding is the AC voltage input terminal, and the secondary winding is the AC voltage output terminal. The output voltage of the secondary winding is proportional to the number of turns of the coil. A single-phase transformer can convert high-voltage power supply into single-phase low-voltage for use in various equipment. For example, AC 6600V high voltage can be converted into AC 220V low-voltage through a single-phase transformer to supply power for lighting or other equipment. The single-phase transformer has a simple structure, With the advantages of small size and low loss, it is suitable for use in low-voltage distribution lines (below 60Hz) with less load.

    Prepare a set of 240V single-phase power supply.

    Connect 240V to the transformer

    Connect 240V to the input terminal of the transformer.

    Lead out 110V/120V power supply.

    119V transformer

    The voltage at the output terminal was measured to be 119V.

    Use this 115V single-phase motor for testing.
