Lightning varistor precautions (2)

2 The operating voltage of the lightning varistor (the voltage applied continuously across the lightning varistor) must not exceed the "continuous operating voltage" value listed in the technical parameters table of the lightning varistor.

3 Lightning varistor operating temperature should be within the range of technical conditions.

4 Lightning varistors should not be installed close to heat or combustible components. It is better to have more than 3mm intervals to avoid damage to components.

5 The surge peak current through the lightning varistor should not exceed the "peak current" listed in the lightning varistor technical parameter table.

6 When the surge pulse is repeatedly applied to both ends of the lightning varistor intermittently for a short period of time, the designer should calculate the average power at this time and should make it lower than that listed in the technical parameters table of the lightning varistor. Out of the "static power."
