Rrymat e qarkut të shkurtër në instalimet ndihmëse të ushqimit të rrymës së vazhduar në impiantet e fuqisë dhe nënstacionet - Pjesa 2: Llogaritja e efekteve

Short-circuit currents in d.c. auxiliary installations in power plants and substations - Part 2: Calculation of effects

Scope

Describes a method for calculation of the mechanical and thermal effects on rigid conductors caused by short-circuit currents in d.c. auxilliary installations in power plants and substations, as described in EN 61660-1. Provides a method which has wide application and which gives results of sufficient accuracy. The calculation method is based on substitute functions, which cause approximately the same maximum stresses in the conductors and the same forces on the supports as the actual electromagnetic force.
