Dear Abdul ;

First, the exact connections for ” MV/LV Transformres ” are : Delta for primary, and Star fro secondary.

Normally, most of Medium Voltage Networks are ” 3 Phases ” only, that means without Neutral, so, the connection’s of the transformer’s primary should be ” Delta “, and as we need for Single Phase Loads the ” Neutral “, the connection’s of the transformer’s secondary should be ” Star “.
