The use of virtual simulation in industrial design and validation processes has considerably increased over the last years, due to better algorithms, affordable computational power with good performance and gradual acceptance of its results by technical experts. Nevertheless, although electromagnetic simulation has also evolved, it still does not have the same penetration in validation processes as...
High performance computing (HPC) platform power delivery simulation is typically based on state average mode for simplicity. However, it is not able to capture the dynamic ripple noise and non-linear effect of output voltages, as well as the phase information. The correlation between state average model and lab measurement often lacks accuracy in low to middle frequency range. As a result, platform...
The arc behavior in the current zero region is critical in the case of very steep rising TRV, such as after clearing a short-line fault. Therefore, intensive and abundant shortline fault tests (L90) of a 245 kV SF6 circuit breaker were performed at the KEMA High Power Laboratory. For the purpose of a comparative analysis three different sets of data were obtained during the tests: 1) High-resolution...
