Tips: Functions of 800 VA Isolation Transformer

Anti-interference effect: This 800 VA isolation transformer can prevent the transmission of some harmonic waves after a Y/△ wiring connection.
Impedance conversion effect: Increase the system impedance, thus making it easy to cooperate with the protective device.
Stabilize the system voltage: When starting a heavy load equipment, the transformer helps reduce the impact on the system voltage.
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).
Reduce the short-circuit current: When there's a short-circuit at the load side, it restricts the short-circuit current of the system.

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.

Great value

This single phase isolation transformer tests fine and it isolates the mains well, just what I needed.
