Sentence examples for fault sequence from inspiring English sources

The chapter's discussion on risk covers topics such as the hazard control hierarchy, fault sequence analysis, probabilistic risk assessment, and more.

When there is a fault in the network, node voltages have no directionality according to fault sequence analysis.

Cyclostratigraphy (sedimentary figures, syndepositional faulting, sequence stratigraphy and framework) and laboratory investigations (petrography, geochemical evaluation) were made of these chalky series, to develop a sequence model for the Metlaoui group and clarify the main relationships between global sea-water level changes, lithofacies repartition and source-rock potential.

They said there seemed to be no single fault or sequence of faults readily explaining the communications failure.

Nonlinear simulation tests are carried out using a fault test sequence applied to a two engine two propeller system.

The adaptive zone-1 algorithm uses two criteria: (1) online SIR calculation using prefault and fault positive sequence voltage and current measured at relay location and (2) the maximum value of the transient monitor function obtained from the three-phase voltages to discriminate the in-zone fault from out-of-section fault.

When the wind farm outgoing line has a single phase-to-ground fault, zero sequence current will become the main component and consequently, the three-phase fault currents tend to become similar indicating obvious weak power characteristic (the results of two phase-to-ground faults are similar).

Open image in new window Fig. 6 Fault zero-sequence current waveforms in wind farm Table 3 Harmonic analysis of fault zero-sequence current Number of wind generators 1st harmonic (A) 3rd harmonic (A) 3rd/1st ratio 0 48.3 9.9 20.5 1 48.7 9.6 19.7 2 49.4 9.4 19.1 4 50.3 8.3 16.5 8 52.8 5.9 11.2.

The mostly adopted HIF detection algorithms are based on the 3rd harmonic characteristic of the fault zero-sequence currents, whereas these 3rd harmonics are very easy to be polluted by wind power back-to-back converters.

A relatively new idea in tectono-sedimentology that has been successful in hydrocarbon exploration is to analyze response relationships between syndepositional faulting and sequence stratigraphic patterns, sedimentary infill features, and the configuration of source, reservoir and seal (Gawthorpe and Leeder 2000; Devault and Jeremiah 2002; Lin et al. 2005; Liao et al. 2012).

Different directional methods are mentioned below: First method uses the phase angle difference between negative sequence fault current and fault voltage (( {phi}_1=angle {overline{I}}_{2mathrm{FSPT}}-angle {overline{V}}_{2mathrm{FSPT}} )).
