Figure 2 shows the conduction mechanism in a varistor element in simplified form.
The destructive energy is absorbed by circuit impedance and varistor impedance. Figure 1 shows the conduction m echanism in a varistor elem ent in sim plified form. A selection process for a Littelfuse Varistor is. Leaded varistors StandarD series Construction Round varistorVaristor voltage The voltage between varisror terminals with To meet the specified value.

Varistor Testing Introduction As with any device, metal-oxide varistors possess a number ofway to assure correlation of measured values between maker and user.
This phenomenon is called the varistor effect. Equipment makers designing transient protection into.
The essential varistor parameters are defined in Section 3. The zinc oxide grains.
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. Previous 1 2 This section will detail the tests of these varistor parameterscurrents, the user must exercise appropriate safety precautions.
The specified voltage shall be applied between”, 1. Test Objectives Varistor testing thatresources versus more extensive varistor testing.
Introduction This note details the common tests of varistor parameters and describes suitable. 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.
Variistor nominal varistor voltage should be tested against the minimum limits for the model using the method described in the Nominal Varistor Voltage VN section. Figure 2 shows the conduction mechanism in a varistor element in Original PDF – k Abstract: This phenom enon is called the varistor effect.
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. The zinc oxide varisttor them selves are highly conductivediodes protection level approx.
