Fig. 5From: Three-phase distribution transformer connections modeling based on matrix operation method by phase-coordinatesBlocks of the transformer admittance matrix YT; the blocks of YT are showed. The self-impedance and mutual-impedance are reflected in Block 1 on the primary side. And self-impedance and mutual-impedance are reflected in Block 4 on the secondary side. Mutual-impedance are reflected in Block 2, 3 on the primary and secondary sideBack to article page
