PROBLEM
An unbalanced three phase
network of pure resistance draws currents of 10. 10 and 14.14 amperes
respectively from the R, Y and B lines of a three phase balanced supply. Find
the symmetrical components of the line currents, if the load is delta
connected.
PROBLEM
Prove that (i) positive
sequence of the line component is equal to [(a – 1) / a ] x positive sequence
of the phase voltage.
Prove that (i) negative
sequence of the line component is equal to [(a^2 – 1) / a^2 ] x positive
sequence of the phase voltage.
