The changes can be used to measure how temperature changes. You can google on varistor or thermistor testing or measuring to learn more about what they should look when measured. Resources. You can google on varistor or thermistor testing or measuring to learn more about what they should look when measured. Metals of different types, especially copper, tungsten and aluminum, change certain properties as they become hotter or colder. NTC thermistor is mainly used to suppress surge current. Varistor Voltage-Current Characteristics . 2 Applications. In order to explain the working of a Varistor, let’s use its VI characteristic shown in figure below to understand it better. NTC thermistor is a temperature-sensitive resistor made of negative temperature coefficient (NTC) and special semiconductor ceramic materials. In contrast to a diode however, it has the same characteristic for both directions of traversing current. It has non-linear voltage current behavior, similar to zener diode. The term thermistor is a contraction of the words "thermal" and "resistor". Varistor symbol. Thermistor probes and assemblies are invaluable for sensing temperature in a variety of industries ranging from HVAC/R and environmental controls to automotive and white goods. | The aging failure of the varistor will initially appear to be almost short circuiting, but if the varistor does not have a thermistor in series or a resistance wire to limit the current, the circuit will eventually open.
