Analysis of Surge Propagation with Lightning Arrester using FDTD for 25 kV-AC Transmission Line [PDF]

, 2017
This paper analyzes lightning surge propagation and reflection as the surge arrives at a lightning arrester. Telegraphist equations have been used to characterize the voltage and current of a travelling wave in a lossless power transmission line and ...

Effect of sintering temperature on microstructure and nonlinear electrical characteristics of ZnO varistor

, 2018
The nonlinear properties of ZBMCCS-based varistors, which are composed of ZnO–Bi2O3–MnO2–Cr2O3–Sb2O3–Co3O4 and SiO2 are studied inrelation to sintering temperature, in the range of 1280–1350∘C.

Solid state compatibility in the ZnO-rich region of ZnO-Bi₂O₃-Sb₂O₃ and ZnO-Bi₂O₃-Sb₂O₅ systems

Boletín de la Sociedad Española de Cerámica y Vidrio, 2010
The obtaining of ZnO-Bi2O3-Sb2O3 (ZBS) based varistor thick films with high non-linear properties is constrained by the bismuth loss by vaporization that takes place during the sintering step of these ceramics, a process which is yet more critical in the

Indirect Method of Moisture Degree Evaluation in Varistors by Means of Dielectric Spectroscopy

Energies
Varistors, due to their unique properties, are materials commonly used in surge protection devices. Their reliability, however, requires periodic inspection, which should specifically include assessment of their moisture content.

Rural Facility Electric Power Quality Enhancement [PDF]

, 1991
Electric power disturbances are known to be more prevalent in small, isolated power systems than in larger interconnected grids which service most of the United States. This fact has given rise to a growing concern about the relative merits of different
