A 3-bus power system network consists of three transmission lines. The bus admittance matrix of the system is
\(\left[ {\begin{array}{*{20}{c}} { - j6}&{j3}&{j4}\\ {j3}&{ - j8}&{j5}\\ {j4}&{j5}&{ - j10} \end{array}} \right]pu\)
Which of the following statements is/are true?
1
The shunt element connected at bus 1 is the shunt inductor
2
The shunt element connected at bus 3 is the shunt capacitor
3
The series reactance connected between bus 1 and bus 3 is j4 pu
4
If all the shunt elements are removed, the value of 3rd row 3rd column element of the Ybus matrix is -j9 pu
