A strong electric power industry having diverse generation sources is a key for advances in the industry, agriculture, technology and standards of living for any nation. In the last few decades, the nuclear power industry has emerged as a strong competitor in the electric power production market due to its less carbon oxide emission, high capacity, and efficiency. The reliable operation of nuclear power plants is heavily dependent on the safe operation of the low voltage instrumentation and control and power cables, which are mostly installed in the containment area and are under thermal and radiation stresses which may decrease the expected life of the cable. In this research work, the behavior of Choloro-Sulfonated Polyethylene /Cross-Linked Polyethylene based low voltage nuclear power plant power cable samples under thermal stress have been studied with the help of non-destructive extended voltage response method. The effect of the thermal stress on the expected life of the cable are also discussed.
Many industries rely heavily on ESPs (electrostatic precipitators). They exist primarily as air filters to prevent hazardous particles from entering the environment. Duct-type ESPs are widely used, have a simple design, and rely on corona wires and collecting plates as their primary arrangement. Numerous studies have been conducted to demonstrate that changing the geometrical shape can aid in improving particle collection efficiency. Wavy plates, W-types, and other designs, for example, have shown to improve particle collection efficiency in a positive degree. The goal of this study is to see what happens when two different types of collecting plates are combined and used together. The proposal is to combine half wavy and half W-type collecting plates and examine them with corona wires with circular shapes. As a result, after completing the numerical study and comparing the results, it is clear that the levels of particle collection efficiency for the various particle sizes have increased with this proposed design. Furthermore, six cases are presented with this design, and the results describe the electrical properties and their magnitude distributions. In fact, in all of the cases presented, this type of combination increased particle collection efficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
