PowerPlasmaChecker is a handy toolkit for power systems and plasma labs. It helps plan relay zone reach and set safe UFLS/UVLS stages with ease. You can check time alignment for synchrophasors and spot any clock skew. For vacuum work, it estimates pump-down time and base pressure. It also guides sputtering by linking power to deposition rate. You can compute mean free path, Knudsen number, and Debye length for quick checks. It converts plasma frequency and electron density, and estimates ion range in targets. There’s even a simple helper to set up Langmuir probe bias sweeps.
