I have got a simple network for my assignment:
I know bus admittance matrix have certain properties that let us form the matrix without writing so many lines of
KCL. But is there any property such that one could, without matrix formation, say
sum of values in row 2 of the matrix is zero, whereas the sum of values in row 4 is –j1?
I have formed the admittance matrix and I can confirm that above statement is true but I was wondering what is the rationale behind that statement?
