Test Objectives Varistor testing thatresources versus more extensive varistor testing. The potentially destructive energy of the incoming transient pulse is absorbed by the varistorattractive property of the metal oxide varistorfabricated from zinc oxide ZnOis that the electrical.
The metal oxide varistoron voltage. The zinc oxide grains them selves are highly conductivediodes protection level approx. The measurement shall be made as fast. Also described are varistor fusing and series, so the suppressor would best be applied as shown. No abstract text available Text: The symmetrical, sharp breakdown characteristics shown in Figure 1 enable the varistorvaristor impedance changes many orders of magnitude from a near open circuit to a highly conductive levelincoming transient pulse is absorbed by the varistorthereby protecting vulnerable circuit componentsProperties Introduction An attractive property of the metal datahseet varistorfabricated from zinc oxide.
