LV network

Estimate fault level and voltage drop along a radial cable path using source and segment impedance.

Radial source-plus-cable impedance approximation. Not a meshed load-flow, full fault study or protection assessment.

Method and assumptions

Radial source-plus-cable impedance approximation. Source impedance comes from the entered fault level or stated impedance, with an R+jX branch ladder to the study bus. Not a meshed load-flow, full fault study or protection assessment.
