About This Launch
GridCircuits offers free in-browser engineering tools for substation, protection and transmission engineers. Its arc-flash energy scaling calculator shows its formula with a worked example, runs entirely in the browser and never uploads project data. It scales incident energy by arc duration only, for preliminary design and education, and is not a full IEEE 1584 calculation.
Why I Built This
Substation and protection engineers needed quick, transparent calculations they could check themselves, without installing software or uploading project data, so GridCircuits built free in-browser tools that show every formula.
