Web5 mrt. 2016 · To find this value, we must multiply symmetrical breaking current by √2 to convert this from r.m.s. to peak, and then by 1·8 to include the “doubling effect” of maximum asymmetry. The total multiplication factor becomes √2 × 1·8 = 2·55. ∴ Making capacity =2·55 × Symmetrical breaking capacity (iii) Short-time rating:
