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.
