QUESTION $2$

An $11kV,3-$phase cable has an impedance of $(5\mathrm{.}24+j6\mathrm{.}4)\frac{}{?}$ phase and susceptance of $950\frac{s}{p}$hase. The line delivers $1\mathrm{.}7$ MVA at $0\mathrm{.}9$ pf lag. Use the nominal T equivalent circuit to determine:

a$)$ sending end current

$(5$ marks$)$

b$)$ sending end voltage

$(5$ marks$)$

c$)$ sending end power factor

$(5$ marks$)$

d$)$ draw the phasor diagram

$(5$ marks$)$
