Question
plase answer  a quesion option corrctly 
 
12./
VS= 1200<0º V

ZL= 50 + j60 ohm

ZS= j25ohm

By taking Zbase = 100 ohm, find Vs (p.u), Zs(p.u), ZL(p.u)

A.

Vs (p.u)  = 1 < 00 p.u

Zs(p.u) = j0.20 p.u

ZL(p.u) = 66.42<39p.u

B.
Vs (p.u)  = 1 < 00 p.u

Zs(p.u) = j0.25 p.u

ZL(p.u) = 42.96<73p.

C.
Vs (p.u)  = 1 < 00 p.u

Zs(p.u) = j0.25 p.u

ZL(p.u) = 0.781<50.2p.u

 

13. Which of following equivalent per unit is inaccurate?

A /Pp.u = p actual / p base per unit 

/Vp.u = V acual / V base per unit 

C / Ip.u =  actual / I base  per unit
