The load shown in the figure is supplied by a $400$V (line-to-line), $3$-phase source (RYB sequence). The load is balanced and inductive, drawing $3464$ VA. When the switch $S$ is in position $N$, the three watt-meters $W_{1}, W_{2},$ and $W_{3}$ read $577.35$W each. If the switch is moved to position $Y$, the readings of the watt-meters in watts will be:

  1. $W_1=1732$; and $W_2=W_3=0$
  2. $W_1=0$; $W_2=1732$; and $W_3=0$
  3. $W_1=866$; $W_2=0$; and $W_3=866$
  4. $W_1=W_2=0$ and $W_3=1732$
