Optimizing Recloser Performance with Simulation
During snow storms or windy days, a branch might break and short-circuit a power line’s electric current as it falls. The first task of a recloser is to interrupt this short-circuit, i.e. to open or disconnect the affected overhead line from the feeding network source. The second task is to try to re-establish power after a short time by to re-closing the line, taking advantage of the fact that most of the reasons for a short-circuit of an overhead line […]
Mersen Simulates Joule Heating in Busbars and Fuses
Joule heating is a fairly standard type of simulation for COMSOL users nowadays. It involves solving for electrical voltage and temperature fields simultaneously with highly temperature-dependent material properties. Controlling Joule heating is very important when designing and manufacturing electrical systems components. The electric protection group at manufacturing company Mersen France used to base their busbar and fuse designs on trial-and-error, but these days they turn to COMSOL Multiphysics.
Thermometer Calibration: When Experimentation Falls Short
The International Temperature Scale of 1990 (ITS-90) is the industry calibration standard for measuring temperatures throughout the world. The National Physical Laboratory (NPL) works to establish and maintain the ITS-90 through experiments, most notably, thermometer calibration. To better understand and overcome the shortcomings of the experimental process, Jonathan Pearce, at the UK’s National Physics Laboratory, turned to simulation. His results yielded fascinating results about the microscopic behavior of the liquid-solid interface during the freezing process.
ABB Uses Electrostatic Simulation to Design Tap Changers
Households and industries alike depend on reliable electrical power. To serve the diverse power needs of end users and consumers, the electrical grid is undergoing a major overhaul to upgrade a technology that is over 100 years old. The new infrastructure — the smart grid — is being developed for reliable, economic, and environmentally friendly electrical systems. A great example of equipment for the smart grid comes from ABB. Along with many other products, ABB has introduced the world’s fastest […]
