  • Considering seismic interaction effects in designing steel supporting . . .
    The 750 kV surge arrester has a fundamental period of 0 77 s, and the value of T g of the GB spectrum (soil III) is 0 65 s, then no turning point is resulted, as observed in Fig 17 (c) On the other hand, displacement response decreases monotonically with increasing flexural rigidity of supporting structure for porcelain surge arresters of all
  • Arrester - an overview | ScienceDirect Topics
    An arrester can be considered a replica of an HRC fuse While a fuse is a current limiting device and protects the connected equipment by limiting the prospective peak fault currents, I SC (Figure 12 18) an arrester is a voltage limiting device and protects the connected equipment by limiting the prospective peak surge voltage, V t (curve 3, Figure 17 21)
  • Analysis for the mechanism of transmission conductor breakage induced . . .
    The arrester model in this case is YH10CX-192 560, which is an externally gapped line arrester (EGLA) Its rated voltage is 192 kV, residual voltage is 560 kV, gap distance is 850 mm, and discharge current is 10kA The installation of this type of line arrester is shown in Fig 3 One end of the EGLA is connected to the bracket and grounded
  • A new on-line leakage current monitoring system of ZnO surge arresters
    The lightning surge arrester should be an insulator at any voltage below the protected voltage, and a good conductor at any voltage above, to pass the energy of the lightning strike to the ground [1] However, zinc oxide (ZnO) element does not have an infinite impedance, so it will draw a continuous quiescent current at normal working voltage
  • Surge arrester optimal placement in distribution networks: A decision . . .
    This mechanism determines how the arrester responds to overvoltages and diverts excessive energy away from the protected equipment A comprehensive study of transfer voltage mechanisms enables the identification of optimal arrester characteristics and configurations that effectively suppress overvoltages [25], [26], [27] Also, in the
  • Simplified Modeling of Metal Oxide Surge Arresters
    The arrester product of Siemens 10 kA, 21 kV (a) The fast front current surge (0 5μs); (b) The standard impulse current surge (8 20μs) Fig 12 The arrester product of Ohio Brass 10 kA, 21 kV (a) The fast front current surge (0 5μs); (b) The standard impulse current surge (8 20μs) 6
  • Non-contact measurement method of busbar voltage phase of substation . . .
    The good operating condition of the arrester is very important for the safe operation of the substation equipment [1, 2] It can effectively eliminate the operating overvoltage and lightning overvoltage on the busbar and protect the transformer and other important grid equipment The arrester is generally connected to the high voltage busbar
  • A Wide-Range Model for Surge Arresters: Verification Analysis
    Keywords: EMTP-RV simulation; power transmission system; surge arrester; wide range model; 1 Introduction Surge arrester is a protective equipment used for reducing over voltages caused by lightning and switching surges on equipment by diverting the content of surge current and restoring the equipment to its original c ndition
  • Surge Arrester - an overview | ScienceDirect Topics
    The previously used conventional arrester is commonly referred to as the series gapped silicon carbide (SiC) arrester The nonlinear resistive elements in this arrester are relatively short cylindrical blocks of silicon carbide stacked one atop the other within the arrester housing in series with spark gap assemblies that are generally
  • Metal-oxide surge arrester monitoring and diagnosis by self-organizing . . .
    Finally, two patterns database are constructed The first one is used to identify just the surge arrester operation condition, i e , whether the surge is defective (label def) or not (label ok) The second database is composed by labels that identify not only the arrester condition, but the type of failure present in the equipment
