The influence of different methods for calculating mean absorption coefficients on the arc voltage and velocity an moving in air along parallel busbars is investigated a numerical simulation. radiation model used discrete ordinate method. Planck, hybrid Rosseland calculations three- six-band selection are discussed. Compared with experimental results from published paper, Planck six bands shows...

The main target for a commercially successful solar cell production is to decrease the cost/Watt-peak ratio. In the last years new techniques like fine line screen printing or plating of the front electrode entered the market. These new techniques enable a reduction of Ag or Ag containing paste of the front grid or even a substitution of this metal. Cu is a suited candidate because of its high ...

Superimposed current components contain effective information, which can be employed to enhance the dependability and security of busbar protection relays. This study aims investigate use slope degree grey incidence analysis model design a methodology for protection. A grey-based criterion has been established inspect similarities superimposed currents measured by nearby CTs inside zone. It is ...

The selection of power distribution components is great importance in electrical facilities. Cable and busbar systems are widely used applications, such as electric vehicle charge stations, microgrids energy storage systems, for the grid. In this study, current on parallel conductors magnetic field distributions around cable structures evaluated studied application where distributed using a sys...

This paper reports on a method combining the use of finite element simulations and external measurements to provide preliminary condition diagnosis oil-filled cable sealing ends (CSEs) without requiring downtime. Good agreement has been obtained between predictions from electric field thermal 132 kV CSE. The electrostatic computation combined with can information regarding distribution inside C...
