DC short circuit — IEC 61660-1
Short-circuit current at the DC busbars of an auxiliary DC installation: the engine superposes the partial current of every DC source (battery bank, smoothing capacitor group, rectifier / DC machine given as an explicit current) over the minimum-resistance cable path, and reports the peak ip, the quasi-steady Ik, the ratio κ = ip/Ik, the loop time constant τ, the rise time and the DC short-circuit power for every selected fault point.
This page needs a scheme before it can calculate
Every study here (load flow, short circuit, harmonics, cables…) runs the real engine on real engineering data, so a scheme must exist first. There is none yet — so instead of an empty page, here is how to start.
GRID-10kV → 1250 kVA transformer → LV bus → 600 kW load + 300 kvar PFC. Loaded in one click; replace the data with yours at any time.
Load the example and continue →In the studio: place devices, wire them, pick models — that becomes your project scheme (exportable drawings / BOM / report).
Open the studio →Use the chat bubble bottom-right, or Contact us — we will set the example to your site parameters.
Note: every number comes from the engine. With no scheme, nothing is invented.
