The KUBS plus Program.

This article presents information about the KUBS plus program. The KUBS plus program is suited for the calculation of three-pole, single-pole and peak short circuit currents in low voltage radial networks. It can determine the backup protection, the selectivity and the voltage drop, and the permissible current loading of cables and conductors, as well as dimension circuit breakers. The program can process up to 250 outgoing electric circuits in any arbitrary arrangement of radial networks. In each outgoing electric circuit it is possible to choose the types of conductor and the conductor material.
