Electrostatic simulation of a 24 kV SF6 gas insulated ring-main unit load break switch

This article is concerned with the features required for a 3D electrostatic computation, using CST EM STUDIO® (CST EMS) of a power engineering application for which a medium voltage SF6 main ring unit load break switch manufactured by ABB Distribution, Skien, Norway [1] has been taken. A CAD model of the equipment was provided with the permission and courtesy of ABB, Bad Dättwil, Switzerland. Electrostatic simulations are used to indicate the locations of critical spots where discharges may occur. For such an analysis, workflow and accuracy are essential requirements. Read full article..

EM Modeling of Aircraft Fuel Systems

EADS, Innovation Works in the UK uses CST EM STUDIO® to aid in the simulation of aircraft fuel systems. EADS has developed an internal code for modelling the filling of an aircraft fuel tank. The code simulates this scenario and outputs the electric field, charge density and potential at various points in the tank and fuel over the filling period. Read full article..

3D EM Simulation of a resistance spot welding gun

This article is concerned with the 3D electromagnetic modelling and equivalent circuit parameter extraction of a Resistance Spot Welding (RSW) gun. The parameters for the gun are not as easily established for the gun as for other RSW system components. The current transformer and electronic converter electrical parameters are either known or can be obtained by standard test procedures. This is not the case for the gun where the electrical parameters are unknown and difficult to measure. A 3D EM simulation using CST EM STUDIO® can be used to establish these parameters and complete the system characterisation. Read full article..
