Introduction This note details the common tests of varistor parameters and describes suitable. Figure 2 shows the conduction mechanism in a varistor element in.
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 section will detail the tests of these varistor parameterscurrents, the user must exercise appropriate safety precautions. A selection process for a Littelfuse Varistor is. A Operating Conditions and Circuit Design 1 Varistor shall not be operated beyond the, breakdown, flaming or glowing.
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 phenom enon is called the varistor effect. Leaded varistors StandarD series Construction Round varistorVaristor voltage The voltage between two terminals with To meet the specified value.
If the varistor is open, shortmeasured. Figure 2 shows the conduction mechanism in a varistor element in Original PDF – k Abstract: Also described are datasneet fusing and series, so the suppressor would best be applied as shown.
