Research on the arcing horn with active arc extinguishing function for HVDC grounding electrode line
The grounding electrode line is an important part of the Ultra high voltage direct current (UHVDC) transmission system. It acts as the channel to conduct the unbalanced current and the grounding current.The arcing horn consists of a pair of electrodes ...

Numerical investigation of the double-arcing phenomenon in a cutting arc torch [PDF]
A numerical investigation of the double-arcing phenomenon in a cutting arc torch is reported. The dynamics of the double-arcing were simulated by using a two-dimensional model of the gas breakdown development in the space-charge layer contiguous to the ...

Study on abnormal abrasion of metro pantograph
Pantograph-catenary system is the central system for the power supply of urban rail transit trains. Higher train speed and complex train operating environment can generate severe vibrations on the pantograph-catenary system, resulting in high-frequency ...

Mitigation of high energy arcing faults in nuclear power plant medium voltage switchgear
A high energy arcing fault event occurred in the medium-voltage (13.8 kV and 4.16 kV) metalclad switchgears in a nuclear power plant not only affecting switchgear but also connected equipment due to the arc energy.

Characterisation of the cold metal transfer (CMT) process and its application for low dilution cladding [PDF]
The process characteristics of the synergic cold metal transfer (CMT) process have been examined for welding aluminium alloy. Utilising a simple backlighting system and through the arc monitoring the droplet transfer modes were identified.

In \(\text{PG}(n,q)\), a \(k\)-arc is a set of \(k\) points such that \(k\geq n+1\) but not \(n+1\) points belong to a hyperplane. A normal rational curve in \(\text{PG}(n,q)\), \(2\leq n\leq q-2\) is a \(q+1\) arc projectively equivalent to the set of points \(\{(1,t, \cdots, t^ n)\mid t\in \text{GF} (q)^ +\}\) where \(\text{GF}(q)^ +\) denotes ...

Three-phase transformer arcing horns; neglected deadly components to birds
Unprotected power transformers are known to create electrocution problems for wildlife. However, the role of three-phase transformer arcing horns and bird electrocutions has not been investigated.

Arc-consistency and arc-consistency again [PDF]
There is no need to show the importance of arc-consistency in Constraint Networks. Mohr and Henderson [9] have proposed AC-4, an algorithm with optimal worst-case time complexity. But it has two drawbacks: its space complexity and average time complexity.

Studi Pengaruh Arcing Terhadap Karakteristik Dielektrik Minyak Sawit
This paper discusses the dielectric properties of palm oil due to the arcing. Arcing was generated by applying a 50 Hz AC voltage at 25 kV level on the needle-plane electrode pair immersed in four type of samples which are different in arcing ...
