چکیده
Abstract Aiming at the problem of fault location for offshore DC cables, this paper analyses reasons why double-ended method is more accurate than single-ended in transmission lines. We point out that error on cables using mainly comes from fact difference wave speed between different segments ignored. Therefore, based traditional method, proposes an improved traveling ranging which considers velocity and actual situation connected sections flexible joint technology.

When viewed from the size of workpieces to be cut, there are only a few machine tools that are positioned between machining centers and large machines. Therefore medium-sized workpieces are often cut by large machines. However, as the tolerance requirements for such workpieces cut by large machines have become tighter and it is difficult to achieve such tolerance only with machine performance, ...

Abstract : This paper proposed a new high-voltage gain resonant switched-capacitor dc-dc converter for high-power offshore wind energy systems. The proposed new dc-dc converter is characterized by the resonant switching transitions to achieve minimal switching losses and maximum system effi ciency. Here, the converter operates at fi fteen times as high as the input voltage with a small device c...

Conclusion: This work has found that AU films have better transmittance than Ag and AI. The 120 , & Au films have -60% transmittance compared to 70% for ITO. Au films with transmittances reaching 80% were also obtained with a corresponding degradation in resistance. The most important aspect to note is that Au films may have promise as transparent contacts. The resistance and transmittance did ...
