Review of Network Topologies and Protection Principles in Marine and Offshore Applications [PDF]
, 2015 An electric fault that is not cleared is harmful in land applications, but in marine and offshore sector it can have catastrophic consequences. If the protection system fails to operate properly, the following situation may occur: blackouts, fire, loss ...

FEATURES OF A FAULTY PHASE AT SINGLE PHASE-TO-GROUND FAULTS
Electrical and data processing facilities and systems, 2022 Relevance Devices for determining the location of fault on power lines assume a known type of short circuit and faulty phases. However, their algorithms, as a rule, can not distinguish the faulty phase. Therefore, the determination of faulty phases during short circuits on power lines is performed by separate devices – faulty phase selectors.

Algorithm for single phase-to-ground fault digital distance relay
IET Generation, Transmission & Distribution, 2012 The value of the potential that appears at the fault location during a ground fault at a high-voltage overhead line depends on many different factors and cannot be considered as an a priori known quantity. Owing to this, the influence of this quantity on the current and voltage measured at one of the line terminals is also unknown so the fault distance

Single-Phase-to-Ground Fault Location Method Based on SOGI
IOP Conference Series: Materials Science and Engineering, 2018 Most fault location methods depend on the exact extraction of fault transient feature. However, due to the weak grounding current, arc grounding and intermittent problems, it is difficult to extract the fault transient feature. Based on second-order generalized integrator (SOGI), a single-phase-to-ground fault section location method for neutral point ...
