This paper presents the impact study of apparent reactance injected by series Flexible AC Transmission System (FACTS) i.e. Thyristor Controlled Series Reactor (TCSR) on the measured impedance of a 400 kV single electrical transmission line in the presence of phase to earth fault with fault resistance. The study deals with an electrical transmission line of Eastern Algerian transmission networks...

New energy systems, such as wind power and photovoltaic distributed supply, in the generation grid-connected transmission system basically will use stronger insulation design, higher operational safety, smaller footprint GIL equipment, while new of smart grid development trend requires accompanying electronic transformer equipment to promote a large area. However, current used systems has cause...

The Transmission part of the power sector is very much important as it deals with huge losses complete sector. substations play a key role in transmission process since generation at plants to final stage consumer end utilization. utmost care should be taken protect these same reduce losses. substation needs protected from blackouts which big problem substations. For this, high voltage equipmen...

The surface charge characteristics of a ±200 kV gas-insulated transmission lines spacer are studied to understand the influence geometry, ion transportation, applied voltage, and gas pressure on distribution. simulation result indicates that geometry simplification would affect A millimeter-level protrusion causes an increase 20 μC m−2 in density. difference 10 is found between simulations base...

Four typical types of artificial defects are designed in conducting the decomposition experiments of SF6 gas to obtain and understand the decomposition characteristics of SF6 gas-insulated medium under different types of negative DC partial discharge (DC-PD), and use the obtained decomposition characteristics of SF6 in diagnosing the type and severity of insulation fault in DC SF6 gas-insulated...

The temperature distribution of the tri-post insulator in a ±500 kV direct current gas-insulated transmission lines (DC-GIL) is investigated. influence thermal gradient on electric field characteristics investigated as well. A horizontally installed GIL model applied simulation. and parameters are measured employed. results indicate that gas shows layered pattern while radial pattern. upper pos...

The reliability of gas insulated substations can be improved by eliminating the effects of metallic particles. The purpose of this paper is to develop techniques, which will formulate the basic equations that will govern the movement of particles like aluminum, copper in uncoated as well as coated Busduct.

The early stages of gas evolution during electrolytic hydrogen production on Au electrodes are characterized by in situ transmission electron microscopy. The results demonstrate that reaction product molecules initially dissolve into solution and then nucleate near, but not on, the electrodes. The gas subsequently wets the electrodes and its successive evolution is governed by triple phase boun...

Gas insulated transmission lines (GIL) have a wide application prospect in special occasions such as cross terrain power transmission. Metal particle pollution is an important reason for the low insulation performance of GIL. When micron metal particles (MMPs), which are most common engineering, adhere to insulators or high-voltage electrodes, will be reduced. Based on that, this paper mainly s...
