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..

Sirona cuts development costs of dental X-Ray equipment with the aid of 3D EM Simulation

Electromagnetic simulation using CST EMS is now established at the heart of these significant improvements to the development and manufacturing processes. The software is extremely reliable, robust and efficient. The CST EMS development team reacts swiftly to our needs and feature requests and is always receptive to new ideas and suggestions. As a consequence, we believe that product support, in addition to the software‘s powerful features, has contributed to the success of EM simulation at Sirona 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..

Low frequency simulation of a Gas Insulated Switchgear

The simulation of a gas insulated switch at 50 Hz is simulated with the low frequency solver in CST EM STUDIO™ (CST EMS). A Pro/E® model is imported, appropriate three-phased sources defined and a simulation performed to obtain the current distributions in the three phase conductors. Read full article..

Electroquasistatic Simulation of a High Voltage Insulator

This article demonstrates the application of the CST EM STUDIO™ (CST EMS) electroquasistatic (EQS) solver to the simulation of a high voltage insulator. It also demonstrates the difference between the results obtained from the EQS Solver and Electro-Static Solver. Read full article..
