Lightning Induced Overvoltages in Mixed 380 kV OHL-Cable-OHL connections

Transmission of electric energy at high voltage levels is mainly performed by overhead lines. Nowadays, an increasing amount of power grid operators are replacing overhead transmission lines by underground cables. Cable presence in power systems may have consequences for the behavior of the total system, since cables have much larger capacitance...

Differential Protection Modeling of the Randstad 380 kV South Ring High Voltage Cable in ATP - EMTP

Modern transmission power networks consist mainly of High Voltage overhead lines, since the later have proven their high operational reliability. However, technological developments have made it possible to use High Voltage cables, not only in the distribution grids, but also at higher transmission voltage levels. Thus, more mixed configurations...

Analysis of Switching Transient Overvoltage in the Power System of Floating Production Storage and Offloading Vessel

Large transient overvoltages can be caused by the switching operation of vacuum circuit breakers of induction motors. In order to analyze the switching transient overvoltage and use an appropriate protective method in the power system of floating production storage and offloading (FPSO) vessel, the accurate models of electrical equipments are...
