The Role Of YO Double Coil

1. Anti-interference effect: After the isolation transformer connected by Y/△, it can block the transmission of some harmonics;

2. Impedance conversion: increase the impedance of the system, so that the protection device can be easily matched;

3. Stabilize the effect of the system voltage: when starting a large load device, reduce the impact on the system voltage;

4. Prevent the grounding of the system: When single-phase grounding occurs on the load side of the isolation transformer, the whole system (the upper part of the isolation transformer) will not be single-phase grounded;

5. Reduce the short-circuit current: When a short-circuit accident occurs on the load side, limit the short-circuit current of the system; other functions.
