The buzzing sound you sometimes hear when walking past high-voltage transmission lines is caused by transformers used for regulating voltage levels. Standard performance and safety regulations require that the noise level be kept within a certain range. In this story, read about how a ... Mehr lesen
FUJIFILM Dimatix, a top producer of commercial inkjet printheads, uses multiphysics simulation to develop MEMS actuators, which their newest ink deposition projects are based on. Chris Menzel, a principal scientist on the research team at FUJIFILM Dimatix, studies printhead actuation to ... Mehr lesen
At STMicroelectronics, engineers use numerical simulation to optimize semiconductor solutions for a wide range of use cases, such as developing a sensor for analyzing concrete health and ensuring the accuracy of a bioimpedance meter. In the case of the bioimpedance meter, an ... Mehr lesen
Designing power transmission lines requires accounting for many factors: mechanical stress due to environmental conditions and hardware loads, performance testing, and--of course--electrical analysis. Transmission line hardware contains both insulating and conducting assemblies. One ... Mehr lesen
NKT HV Cables nutzten numerische Modellierung, um elektromagnetische Felder zu untersuchen und Armierungsverluste in 3D-Kabeldesigns zu berechnen. Die Modellierungsergebnisse werden anschließend mit experimentellen Messungen validiert, um die Verlässlichkeit der simulationsgestützten ... Mehr lesen
U.K. National Grid bears responsibility for maintaining the high-voltage transmission network in the U.K. Determining accurate cable ratings (maximum load capacity while staying within temperature ranges) is a significant effort, since they have to maintain reliability, safety, and ... Mehr lesen
Stromnetze müssen ordnungsgemäß gewartet werden, um sie vor Systemausfällen zu schützen. Die Ingenieure von ABB verwenden Multiphysik-Simulationen, um Messwandler und Sensoren zu entwickeln, die Überspannungen standhalten und unterirdisch eingesetzt werden können. Mehr lesen
ABB, a multinational leader in electrification products and power grid technology, develops generator circuit breakers (GCBs) that safeguard power plants around the world. GCBs must dissipate short-circuit current surges within milliseconds to prevent damage to the grid and power plant. ... Mehr lesen
To speed up the development process for a gas-insulated, metal-enclosed switchgear (GIS), while significantly reducing costs, Pinggao Group used COMSOL Multiphysics®. They also built a simulation application that enabled collaboration on the design throughout the organization. Mehr lesen
Traditional power boxes are bulky and too large. To design a power box that is more space-conscious, modular, and ready for implementation in smart cities, while also ensuring structural and thermal integrity, Raychem RPG is using multiphysics simulation. Mehr lesen
