1. Whether the varistor is extruded or not, the voltage of the varistor decreases obviously until it is zero;

2. Insufficient voltage resistance;

3. Transient overvoltage damage;

4. The number of overvoltage protection;

5. The surge voltage is too large, which is higher than the absorbed power;

6. Aging and failure, the leakage current is increased;

7. Working temperature nearby;

8. The current and surge are too large;

9, Has not passed the quality authentication and so on.
