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：原油的差的质量显然导致油产品，和技术的高硫内容因为原油的desulfurization着急地被需要以便在石油产品的硫内容能从根被减少。这份报纸为原油的desulfurization在技术描述进步。为原油的desulfurization的现在的技术包括苛性的洗的、干燥煤气的desulfurization，hydrodesulfurization(HDS)，etc.The为被学习的原油的desulfurization的新联合技术：静电的领域里的biodesulfurization(BDS)，hydrogenationbacterial催化作用，微波催化的加氢，BDS-OD-RAdesulfurization和氧化desulfurization，和ultrasonic/microwave-catalytic氧化在我们的实验室适用，与他们的发展趋势也被讨论。

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
