AVS high/low voltage pretection

Characteristic

1. When overvoltage occurs in single-phase line, the line is cut off, and the voltage of single-phase line is restored to normal. After delay, the line is automatically reset and connected without manual operation.

When transient or transient voltage occurs in the transmission line, the protector does not malfunction.

3. When the voltage of the line is unstable due to faults such as faulty contacts, or when a sudden power failure occurs and a sudden call occurs, the protector does not connect the line.

When the line fault voltage is the highest, the protector itself will not be damaged.

5. The protective device has anti-time action characteristics, and the action time is less than 1s.
