The customer must return the negative effects of its consumers （taking reactive power, harmonic generation, phase unbalance） down to the prescribed limits. This primarily refers to the presence of non-linear consumers, leading to distortion of the basic parameters of voltage and current, in steady or transient conditions, and therefore the deformation of waveform. One way to reduce the negative feedback effects, especially with inductive loads, is the reactive energy compensation. The paper presents one of the solution for reactive power compensation, applied on the pumping station of public company ＂Waterworks and Sewerage---Bar＂, Bar.展开更多

Under such circumstance efficiency in teaching and learning reading comprehension is increasingly becoming crucial since it constitutes an indispensable part of acquiring English as a second language. The orientation of functional discourse markers at various textual levels in CET reading texts is elaborated upon in this paper to map out one alternative way to contriving an effective reading strategy on the basis of reading test — reading strategy study.展开更多
