Write a matrix equation that determines the loop currents. 24 V 302 492 HH 16 V {592 3122 19 V 25 V m 21 V mo $592 310 {222 3292 For each matrix, let row 1 correspond to loop 1, row 2 correspond to loop 2, and so on. Also, enter positive values for positive voltages and negative values for negative voltages.

What do the connection angles and groups show in transformers? For example, where are the Yy0 , Dy5 ,Yd5, Yz5 group transformers used?

The simultaneous equations representing the currents flowing in an unbalanced, three-phase, star connected, electrical network are as follows: 2.4I1 + 3.6I2 + 4.8I3 = 1.2 −3.9I1 + 1.3I2 − 6.5I3 = 2.6 1.7I1 + 11.9I2 + 8.5I3 = 0   Using Gaussian elimination, solve the equations for the currents.
