This study aims to investigate the impact of lightning masts placement on underground cables within high voltage substations. While subject discharges near has been covered with open cable runs and wind farms in many papers, this focuses events substations considering associated effective zones, which were not available literature. Substations built areas prone activity experience frequent that...

To prevent accelerated thermal aging or insulation faults in cable systems due to overheating, the current carrying capacity is usually limited by specific conductor temperatures. As heat produced during operation of underground cables has be dissipated environment, actual a power system primarily dependent on properties surrounding porous bedding material and soil. investigate dissipation proc...

Abstract Replacing the underground cable steel bracket within service life will increase maintenance cost, so prediction of is aroused. The mechanical properties and atmospheric corrosion carbon are key factors affecting bracket. In this paper, a method brackets considering proposed. First, analyzed by finite element model to determine thickness damage. Based on electrochemical experiments, bas...

workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎however, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...

This paper investigates the effect of metallic sheaths on losses and temperature of medium voltage power cables. Two grounding methods of sheaths, including both ends bonding and single point bonding that causes different situations on cable ampacity, are considered. Electrical losses of cables that are main sources of heat are calculated in both conductor and metallic sheath of the cables. She...
