Plasma torches are used in processing of materials as well as in the energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be initiated by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the plasma is obtained by heating, ionizing and expanding a working gas, introduced into the chamber of the torch ...

The conductivity of seawater directly correlates with the concentration of dissolved salts. This model demonstrates a new approach to the methodology of inductive conductivity measurement of seawater and other liquids. COMSOL Multiphysics® was used to build a parametrically swept model of an O-Core Inductive Conductivity Measurement Sensor for Seawater. This sensor model is built using the ...

Today, low noise is a mandatory feature for power transformers to comply with customer specifications and environmental regulations. Therefore, it is crucial to develop sound prediction tools with sufficient accuracy to avoid overkill margins in design and costly modifications after transformer completion. The paper will focus on core noise which is a typical multiphysics phenomenon involving ...

Efforts involving simulation of transmission line networks necessitate the accurate values of the parameters of the lines. In this paper, as an attempt in estimating such parameters, the parameters of high voltage asymmetric power lines are calculated. In the process of estimation, the three phase equivalent circuit model is used. The resistance and inductance of such lines are dependent ...

COMSOL Multiphysics® software is used to model a water tree in tape shield and concentric neutral cables. It allows for the effect on electric field intensity at the tip of the water tree and electric potential due to the water tree to be better understood. Also, COMSOL is used to calculate the resistance and capacitance of a section of cable with a water tree as it grows across the insulation. ...
