the specific conductivity κ is 56 m/(Ω*mm2)
a 30 % increase in the wire’s resistance covers the thermal behavior and all other effects during a short-circuit event
Select the rated current In and breaking capability Icn of the TS energy storage circuit-breaker, such that
a short circuit event at any point of the TS wire triggers instantaneous tripping
a short circuit event at any point of the TS wire can be interrupted
the maximum possible rated current is chosen, although the value might be well above the typical continuous current rating of the cable
