Blue Origin is assessing damage after a rocket exploded during a test run in Florida on Thursday.
The earthquake was felt widely on the islands of Hawaii, โMaui, and โOahu โ and was at a depth of about 14 โmiles, according to USGS.
Three days into the Iran war, Iranโs Islamic Revolutionary Guard Corps said the quiet part out loud: The Revolutionary Guardโs Qods Force has long carried out plots around the world and now intended to deploy those capabilities against the U.S. homeland. The United States, a Qods Force statement carried on Iranian television warned, โwill no longer be safeโ as the Qods Force targets Americans within the homeland and abroad. โThe enemy should know that their happy days are over and they will no longer be safe anywhere in the world, not even in their own homes.โ U.S. authorities went on a nationwide high alert The post Between Intent and Capability: Assessing the Lack of Iranian Attacks on the U.S. Homeland appeared first on War on the Rocks.
Laboratory or in-field measurements are often considered the gold standard for certain aspects of power system design; however, measurement approaches always have limitations. Simulation can help overcome some of these limitations, including speeding up the design process, reducing design costs, and assessing situations that are often not feasible to measure directly. In this presentation, we will discuss two examples from the power system industry. The first case we will discuss involves corona performance testing of high-voltage transmission line hardware. Corona-free insulator hardware performance is critical for operation of transmission lines, particularly at 500 kV, 765 kV, or higher voltages. Laboratory mockups are commonly used to prove corona performance, but physical space constraints usually restrict testing to a partial single-phase setup. This requires establishing equivalence between the laboratory setup and real-world three-phase conditions. In practice, this can be difficult to do, but modern simulation capabilities can help. The second case involves submarine HVDC cables, which are commonly used for offshore wind interconnects. HVDC cables are often considered to be environmentally inert from an external electric field perspective (i.e., electric fields are contained in the cable, and the cableโs static magnetic fields induce no voltages externally). However, simulation demonstrates that ocean currents moving through the static magnetic field satisfy the relative motion requirement of Faradayโs law. Thus, externally induced electric fields can exist around the cable and are within a range detectable by various aquatic species. Key Takeaway: Learn how to use modern simulation to translate single-phase laboratory corona mockups into accurate three-phase real-world performance for 500 kV and 765 kV systems. Explore the physics behind how ocean currents interacting with HVDC submarine cables create induced electric fieldsโa phenomenon often overlooked but detectable by aquatic species. Gain actionable insights into how to leverage simulation to reduce design costs and bypass the physical space constraints that often stall traditional testing. See a practical application of electromagnetic theory as we demonstrate how relative motion in static magnetic fields necessitates simulation where direct measurement is unfeasible.
