    Tips: Functions of 800 VA Isolation Transformer

    1. Anti-interference effect: This 800 VA isolation transformer can prevent the transmission of some harmonic waves after a Y/△ wiring connection.
    2. Impedance conversion effect: Increase the system impedance, thus making it easy to cooperate with the protective device.
    3. Stabilize the system voltage: When starting a heavy load equipment, the transformer helps reduce the impact on the system voltage.
    4. Prevent system grounding: When a single-phase grounding occurs on the load side of the isolation transformer, it prevents the single-phase grounding from happening to the whole system (upstream parts of the isolation transformer).
    5. Reduce the short-circuit current: When there's a short-circuit at the load side, it restricts the short-circuit current of the system.

    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.
