Since the Bum of the three three-phase currents at every moment
is aefl), the sum of the initial values of the thme transient currents
also is aero. Since the three transient curves <i°, ta°» 4° are pro-
is aefl), the sum of the initial values of the thme transient currents
also is aero. Since the three transient curves <i°, ta°» 4° are pro-
portional to each other fas exponential curves of the same dura-
tion T *» -A and the sum of their initial values is &ero, it follows
