The value of off diagonal elements in Y Bus Matrix is:
- Sum of admittances connected at bus I
- That is connected between bus i and bus j with negative sign
- That is connected between bus i and bus j with positive sign
- Sum of admittances connected at bus j
Correct answer: 2. That is connected between bus i and bus j with negative sign
Explanation: Property of Y bus matrix is that the value of off diagonal elements Yij = Yji , which is connected between bus i and bus j and which is represented with negative sign.
