NON-DESTRUCTIVE TESTING OF THE PHYSICAL AND MECHANICAL PROPERTIES FOR THE ZINC-OXIDE VARIABLE RESISTORS OF DIFFERENT SUPPLIERS
https://doi.org/10.17073/1683-4518-2018-1-60-62
Abstract
The non-destructive acoustic method was used to investigate the physical and mechanical properties of the zinc-oxide ceramic variable resistors manufactured by the leading foreign companies such as ABB, Epcos, as well as by the Saint-Petersburg's Energy-protective Works. The results of this acoustic method are given and discussed in the article in application to the properties determination of the variable disc-shaped resistors with the different diameter-to-height ratio. It was noticed that the dispersivity of the powders which are used in the molding influences the variable resistors' physical and mechanical properties.
