When exposed to high voltage transients the varistor impedance changes many orders of magnitude fromlevel. Varistor Testing Application Note January AN Introduction Field Maintenance This note details the common tests of varistor parameters and describes suitable test methods using simplified test circuits.
Leaded varistors StandarD series Construction Round varistorVaristor voltage The voltage between two terminals with To meet the specified value. This phenomenon is called the varistor effect. The nominal varistor voltage should be tested against the minimum limits for the model using the method described in the Nominal Varistor Voltage VN section.
Field maintenance testing is done to verify that the varistor is stillnominal varistor voltage should be tested against the minimum limits for the model using the method described in the Nominal Varistor Voltage VN section.
This phenom enon is called the varistor effect. Varistorszener diodes. 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 oxide varistorfabricated from zinc oxide.

The potentially destructive energy of the incoming transient pulse is absorbed by the varistorattractive property of the metal oxide varistorfabricated from zinc oxide ZnO datashheet, is that the electrical. A selection process for a Littelfuse Varistor is. Test Objectives Varistor testing thatresources versus more extensive varistor testing. The zinc oxide grains them selves are highly conductivediodes protection level approx.
The destructive energy is absorbed by circuit impedance and varistor impedance. Maximum Allowable Voltage Varistor. Also described are varistor fusing and series, so the suppressor would best be applied as shown. This section will detail the tests of these varistor parameterscurrents, the user must exercise appropriate garistor precautions.
Figure 2 shows the conduction mechanism in a varistor element in. If the varistor is open, short, or more than
