Distributed capacitive current of ultra high voltage and extra high voltage (UHV&EHV) transmission lines has a severe negative effect on current differential protection. The current differential protection in this proposed paper is based on distributed parameters line model of the transmission line and has been used to solve the problem of distributive capacitive current of transmission line. Time-domain algorithm has been used to calculate currents at the set point of the line by using both ends current. By adding linear interpolation with low computational rate at each sampling points has been achieved. The theoretical analysis of this method is broach to demonstrate how the novel principle is of high sensitivity in differentiating between the external and the internal faults of the line. After theoretical analysis and applying the pristine novel principle of current differential protection for UHV and EHV transmission lines based on distributed parameters line model, the simulation results illustrates that the analysis done in this paper is quite appropriate as desired, correspondingly this recently acquired principle is much reliable, compared to the traditional principle.

SEO is the process of taking actions to gain unique traffic from search engines your ranking and place on a search engine website depends on user queries which in turn on what your web page have done for Search Engine Optimization. The Web search engine is faced with a much difficulties, problems in maintaining or enhancing the quality of their performance. These problems are either uncommonly to this domain or novel variants of problems that have been studied in the literature. And the same time webmaster website web page owner facing problem to learn the search engines update policy and page ranking and index systems learn how and that thing keep important to enhance to quality of website web page to top ranking our studies focus new Google panda 4.0 policy update in search engine new Google panda 4.0 is extremely important for and quickly improve ranking of single original fresh website web page to it is keywords in top ranking in search engines. Your client has a website with the same copy used in multiple places push for immediate removal you notice this if you have you post a press release to multiple websites, for examples. The webmasters are more likely to be caught and penalized for duplicate content with the new panda update it is time to start editing and it causes their website to be completely blocked from ranking at all or at the extremely least cause their content to rank far lower than it.

The composite insulation system of power transformers consisting of two insulation materials (cellulose and mineral oil) are the main insulation material of power transformer, the increase of moisture will reduce their insulation strength. Moisture equilibrium curves are the basis of power transformer moisture detection, however, the service data and theory analysis both indicate the present curves are not fit for old transformer. Therefore this research work is focused the law and mechanism of the impact of aging on moisture equilibrium of cellulose and mineral oil. In this paper theory of moisture absorption mechanism and impact factors of cellulose and mineral oil are analyzed. The various aged cellulose and mineral oil samples were analysis by thermal aging method. This research work is also analyzed the moisture equilibrium law and mechanism of cellulose and mineral oil, which have been both theoretical significance and applicable potentials.
