Characterization of electric faults in photovoltaic array systems
Electric faults in photovoltaic (PV) systems cause negative economic and safety impacts, reducing their performance and causing unwanted electric connections that can be dangerous for the user.

Analysis of Single-Phase-to-Ground Faults at the Valve-Side of HB-MMCs in HVDC Systems
Although the probability of occurrence of station internal ac grounding faults in modular multilevel converter (MMC)-based high-voltage direct-current systems is low, they may lead to severe consequences that should be considered when designing ...

Benefits of a 3D geological model for major tunnelling works : an example from Farringdon, east-central London, UK [PDF]
In the design of major construction works, the better the ground conditions are known, the more control there is on the assessment of risks for construction, contract and personnel, and ultimately on final costs. Understanding of the ground conditions is

Single-phase earth ground faults are the most frequent faults likely to occur but hard to identify in a distribution system, especially in a neutral ineffectively grounded system.

Recent anomalous deformation of the ground surface in fault zones: shear or tensile faulting?
Various definitions of the kinematic types of faults are reviewed. The degree of symmetry in the distribution of anomalous displacements of the ground surface is proposed as a morphological criterion for identifying the types of faults based on geodetic ...

Thermal Effects of Ground Faults on MV Joints and Cables
In recent years, an anomalous increase of faults in underground medium voltage (MV) cable lines has been recorded in Italy, especially during summer; the largest number of faults affected cable joints.

Detection of inter-turn faults in multi-phase ferrite-PM assisted synchronous reluctance machine [PDF]
Inter-turn winding faults in five-phase ferrite-permanent magnet-assisted synchronous reluctance motors (fPMa-SynRMs) can lead to catastrophic consequences if not detected in a timely manner, since they can quickly progress into more severe short-circuit
