简介：traditional current differential protection cannot identify such fault for the sake of sensitivity limited by normal load current. RCS-985 Series generator-transformer unit protection is equipped with transformer DPFC percentage restraint differential protection and generator DPFC percentage restraint differential protection. Comparing with traditional percentage restraint differential protection,DPFC percentage restraint differential protection makes use of DPFC in phase current on each side of transformer and DPFC in differential current,Inter-turn fault is the main kind of fault in electric power transformer. It is meaningful that employing sensitive and secure protection to identify inter-turn fault inside power transformer. In RCS-978 series power transformer protection

简介：EAP situations in which certain subjects are taught in English and EAP situations where subject courses are taught in the national language.,In EAP situations where subject courses are taught in the national language,EAP in ESL (English as a second language) situations

简介：thus the sensitivity is high for internal low percentage inter-turn fault without risks of unwanted operation under external fault.,Integration of main and backup protection with duplicate allocation reduces the total number of power transformer protection devices,Lifting differential setting or introducing differential protection with product- quantity restraint will lose sensitivity or even lead to missing operation. With identifying harmonic component and waveform character of differential current asynchronous anti-TA saturation criterion can distinguish between internal fault and TA saturation under external fault.

简介：the research to reading comprehension concept become further and further. Choosing a suitable one to improve students’ comprehensive competence become one of the great important contents to English teaching quality improving of reading. In fact while reading,reading stands at the top of the world. Because of this some teachers and scholars begin to research new teaching methods of English reading in order to improve students’ reading comprehension level. Here,it was valued universally and made a great affection about teaching of English reading. But whether it is good for today’ students that is a question. From 1980s training of reading skills and tactics were stressed meanwhile it pay much attention in textual teaching and the accumulation of language knowledge and culture background information. C） Demands for students Reading as it is an extraordinary difficult course of physical and mental so that it demands us not only to recognize the language marks correctly

简介：study skills and approaches to teaching EAP,EAP work is no doubt playing a more and more important part in a world-wide range due to the increasing demand for study skills training. As a language teaching approach,The genre approach to EAP writing focuses on the teaching of particular academic genres like essays

简介：Split-phase current differential protection has excellent capability of fault phase selection no matter whether the fault occurs on the same line or cross over lines.,under-reaching distance protection will not overreach when fault occurs at the end of line or the beginning of the next line after series capacitor.,The whole protection scheme for double-circuit lines on the same tower consists of split-phase current differential protection or split-phase composite distance carrier protection and zero-sequence directional comparison protection as main protection

简介：DPFC percentage restraint differential protection makes use of DPFC in phase current on each side of transformer and DPFC in differential current,Fault on and near busbar is the most serious fault for electric power system transient state stability. Clearing such kind of fault quickly is key to keep system stability. As to line protection,Inter-turn fault is the main kind of fault in electric power transformer. It is meaningful that employing sensitive and secure protection to identify inter-turn fault inside power transformer. In RCS-978 series power transformer protection
