The effect of repetitive swells on metal-oxide varistors

چکیده
Neither the effects of repetitive swells on metal-oxide varistors, nor the natural occurrence of swells had been documented in the literature. The paper briefly described a laboratory system capable of generating arbitrary swells and applying them to test varistors. A statistical experiment on five lots of varistors was performed and preliminary results reported. Effects of amplitude, duration, and number of swell occurrences were assessed, using as a criterion the change in varistor nominal voltage from before to after the swell sequence.

The Effects of Electrical Degradation on the Microstructure of Metal Oxide Varistor
-In this paper, the findings from systematic experiments with the purpose to determine the degradation effect of single and multiple current pulses on the microstructure of the Metal Oxide (MO) varistor are described. Six distribution class varistors from one manufacturer were used in these experiments. The first part of the paper describes the electrical condition after application of single a...
متن کاملAnalysis of Grading Ring Design Parameters and Heat Sink Numbers Effect on Voltage Distribution and Leakage Current in Metal Oxide Surge Arrester
Metal oxide surge arresters (ZNO) are used widely in power system to protect equipments from over voltages. Non uniform potential distribution leads to the depressed service life and low safe reliability, so grading ring is applied on HV surge arrester order to uniform the electric field distribution. One of the problems of arresters is leakage current in power frequency that different paramet...
متن کاملInternal Protection of Transformer Windings Against Transeint Surges Using ZnO Varistors
Power system overvoltages due to switching, lightning and other disturbances are the main problem for designers of the power transformers. Once some frequencies of the incoming surges match with some of the natural frequencies of transformer winding, the resonance phenomenon is expected in transformer winding. The resonant overvoltages may destroy the insulation between turns and cause to insul...

متن کاملThe effect of composition on flash sintering parameters of varistors based on ZBS
Flash sintering is one of the latest sintering processes of ceramics, which has recently attracted the attention of researchers due to its high sintering speed and significant energy reduction. An essential feature of successful flash is negative temperature coefficient (NTC) semiconductor behavior. In this research, the flash sinter process of ceramic varistor based on ZnO-Bi2O3-Sb2O3 (ZBS) ha...
