The working principle of the arrester is actually the working condition of the varistor, which is realized by the characteristic curve of the varistor. When the voltage reaches the inflection point of the voltage, the arrester begins to conduction. With the increase of the voltage, the current begins to soar, so as to limit the over-voltage value, so as to protect the electrical equipment.
