    Tips: Other functions of the isolation transformer
    An isolation transformer is added for personal safety when using some electrical appliances. For example, when repairing a color TV set, the maintenance personnel may suffer from an electric shock if he contacts this circuit accidentally because the power supply unit of the color TV set is connected with the electric supply, thus endangering his personal safety. When repairing some household appliances, the isolation transformer should also be connected. The connection method is: Connect one connector of the isolation transformer to the socket and the other connector to another socket firstly, then connect the repairing household appliance to the socket where the isolation transformer is connected.

    Need more detail of ATO isolation transformer? Here is a good explanation about it in this video. To test the accuracy of the transformer voltage, we take a 3000 VA single phase 220V iuput to 110V output isolation transformer as an example.
