We study the problem of designing fault tolerant routings in both complete and complete bipartite optical networks. We show that this problem has strong connections to various fundamental problems in design theory. Using a design theory approach, we find optimal f-fault tolerant arc-forwarding indexes for all complete networks and all complete balanced bipartite networks. Similarly, we find alm...

An arc fault is the leading cause of electrical fire. Aiming at problems difficulty in manually extracting features, poor generalization ability models and low prediction accuracy traditional detection algorithms, this paper proposes a method based on fusion channel attention mechanism residual network model. This to perform global average pooling information from each feature map assigned by b...

A current-voltage composite controller for an arc suppression inverter is designed. The current and voltage at the fault point are reduced by injecting regulating neutral to completely eliminate risk of fire overvoltage caused a single-line-to-ground arc. cascaded used, effects ground parameter measurement, line impedance drop, harmonic coil on control, control methods analysed compared. Finall...

Even though shunt compensation of transmission lines (TLs) is a common practice to limit the overvoltages stemming from Ferranti effect, it may cause transient and steady-state resonant when one phase left open due single-pole-open condition following temporary phase-to-ground (Ph-g) fault. Furthermore, existing reactors potentially increase duration secondary arc current at fault point hence p...

In the non-effectively grounding distribution system, residual current under single-line-to-ground (SLG) fault threatens safety of human being and power supply equipment. Active arc suppression device has been proved to be effective for SLG when line impedance is ignored. However, in practice, varies with location load flowing through brings about additional voltage drop, which increases not de...

The arc-suppression coil (ASC) in parallel low resistance (LR) multi-mode grounding is adopted the mountain wind farm to cope with phenomenon that misoperation or refusal of zero-sequence protection LR farm. If fault disappears before put into system, it judged as an instantaneous fault; while does not disappear after a permanent single-phase (SLG) criterion based on power variation proposed id...

The Jura-Cretaceous Peninsular Ranges batholith (PRb) of southern and Baja California is a remarkable example of a zoned batholith containing distinct oceanic (western) and continental (eastern) basements. The transition between these basements is marked by a crustal-scale boundary along which distinct volcanosedimentary, structural, and metamorphic histories evolved during Mesozoic orogenesis....

Arcing faults are a great concern in any electrical installation. However, and despite all precautions, the probability of occurrence can't be equal to zero. The paper discusses situations, effects and how mitigation of these effects can be seeked through design choices during the design stage of the installation. Arc-proof switchgear is contributive, but can't address all the situations, nor c...
