Three-Phase Systems in Power Applications - Engineering

Q1:

In a Y-connected circuit, the magnitude of each line current is

A one-third the phase current

B three times the corresponding phase current

C equal to the corresponding phase current

D zero

ANS:C - equal to the corresponding phase current

You Can remember easily like word, SIDE.

S - Star, I-Current, D-delta, E-emf(voltage).

SI - in Star Connection Currents Are Same I(L) = I(Ph).

DE- In Delta Connection emf(voltage) Are Same V(L) = V(Ph).
