Describe briefly the breakdown of liquids below intrinsic strength due to 3 types of
impurities.

Expert Solution

In the case of commercial insulating liquid, which may not be subjected to very elaborate purifying treatment, the breakdown strength will depend more upon the nature of impurities it contains than upon the nature of the liquid itself.These impurities which lead to the breakdown of commercial liquids below their intrinsic strength, can be divided into the following 3 categories

(a) Impurities which have breakdown strength lower than that of the liquid itself (ex: bubbles of gas). Breakdown of the impurities may trigger off the total breakdown of the liquid.

(b) Impurities which are unstable in the electric field (ex: globules of water). Instability of the impurity can result in a low resistance bridge across the electrodes and in total breakdown.

(c) Impurities which result in local enhancement of electric field in a liquid (ex: conducting particles). The enhanced field may cause local breakdown and therefore initiate complete breakdown.

Explain how liquids can be analyzed by gas chromatography. Briefly define or describe the function, in gas chromatography, of the carrier gas: stationary liquid phase: solid support: If ethyl acetate and n-butyl acetate are analyzed by gas chromatography, which of these esters will generally produce a peak with the shorter retention time? What operating variables determine retention time? Explain why is it important to inject the sample quickly.

The table below contains observations of breakdown time of 3 different machines at a manufacturing site. The production manager believes that the main reason for machines breaking down is the difference in quality of raw material that comes from 3 different sources. On the contrary, the procurement department, which is responsible for supplies, considers as the main reason the old age of some production machines and their poor maintenance. Some young machine operators believe that the problem is more complicated;...
