The most essential asset of any country that can boost its development or can destroy it, is electricity. Electricity theft prevention or non-technical loss detection has become major problem around the globe for every developed or under develop country to maintain its status in global society. Every month and every year many researchers, scholars and university students presented their studies, ideas and proposed their electric management system for prevalent of nontechnical energy loss detection in transmission line. The core objective of this survey is to highlight the existing solutions, their effectiveness in terms of performance and accuracy and their applicability. This will help in finding a diverse and reliable solution, understanding what others possible methodologies and techniques can be adopted in order to overcome current transmission supply challenges and improve the existing solution that can promptly address electricity prevention issues.
Plastics as air-liquid desiccant contacting surfaces are being explored as a promising alternative to metallic surfaces in falling film towers. Nevertheless, poor wetness of plastic has severely restricted its extensive practical applicability. In the current experimental study, surface modification technique is employed to enhance the dehumidification performance of single polypropylene plastic plate surface. Dehumidification ability of three kind of plastic plate surface: Plain PP plate, Modified PP plate A and Modified PP plate B were investigated and compared in an adiabatic vertical falling film tower. It was found that the best Modified PP plate offered 48.1 - 127.0% improvement in dehumidification effectiveness as compared to the Plain PP plate with an average improvement of 83.3%. Furthermore, a new correlation is developed to predict the dehumidification effectiveness of plastic and metallic surfaces of adiabatic/non-adiabatic falling film tower by incorporating the wetting factor and sensible cooling information in the correlation equation. The new approach takes into the account the sensible cooling (non-adiabatic absorber) of the desiccant solution in the upper half of the absorption column. The proposed correlation demonstrates excellent accord with eleven experimental datasets, with an average error of 12.7%.
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.
