A new pilot directional protection method for HVDC line based on the polarity of inductive energy
IET Generation, Transmission & Distribution, 2021 Concerning the poor immunity of DC line protection to fault resistance in the case of internal fault and its mal‐operation proneness in the case of external fault, a new pilot directional protection scheme for HVDC line in AC/DC hybrid system based on ...

A transient and non-unit-based protection technique for DC grids based on the rate-of-change (R-o-C) of the fault induced travelling wave components [PDF]
, 2019 This paper presents a transient and non-unit-based protection scheme for consideration in DC grids of the future. The technique utilises the rate-of-change (R-o-C) of the associated travelling wave components following the occurrence of a fault to ...

A transient based protection technique for future DC grids utilising travelling wave power [PDF]
, 2018 This study presents a novel time-domain protection technique for application to DC grids. The technique utilises the power developed by the forward and backward travelling waves produced by a fault to distinguish between internal and external faults. For

Internal faults in power transformers
IET Electric Power Applications, 2007 The paper deals with internal faults in large power transformers. The explanation of such faults is followed by the description of an analytical method proposed for the calculation of the power flow during an interturn fault, including the current supplied by the power grid, the current in a group of short-circuited turns and the current in the spot of

Internal representation of a process, fault diagnosis and fault correction [PDF]
Ergonomics, 1979 This paper reports on an investigation into the relationship between the internal representation of a process on the one hand and on the other, control behaviour when diagnosing and correcting faults. The subjects were 87 process operator trainees, performing certain tasks in a simulated process control situation.
