    Tips: Dry type step up & step down isolation transformer cooling method

    Dry type step up & step down isolation transformers mainly include natural air type and forced air type. Natural air cooling is mainly for transformers which are continuous operating within the rated capacity. Forced air cooling method can make the output capacity of the transformer increase by 50%. This method is mainly applied to discontinuous load operation or load operation due to accidents. However, both the impedance voltage or load loss will not increase naturally during the loading operation and they are not conducive to economic operation, so it is not appropriate to make the transformer run under suchload for a long time.

    How to Test Step Up & Step Down Isolation Transformer?

    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.
