If the varistor is open, shortmeasured. No abstract text available Text: 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 elec trical behavior of the metal oxide varistorasimplies that the electrical properties are controlled by the physical dim ensions of the varistor: When exposed to high voltage transients the varistor impedance changes many orders of magnitude fromlevel.

The zinc oxide grains. This phenom enon is called the varistor effect. Figure 1 shows the conduction m echanism in a varistor elem ent in datsaheet plified form.
