To make the transformer connections compatible with three phase supplies we need to connect them together in a particular way to form a three phase transformer configuration. The above figure shows the connection diagram of an open delta system. For the three phase transformer the high voltage phase terminals are designated by the letter h.
Requires 1 isolated mv terminal for each transformer.
The above figure shows the connection diagram of an open delta system. The first symbol indicates the connection of the primary and the second symbol is the connection of the secondary. Each transformer is rated as 10 kva current rating is 10 a and voltage rating is 1000 v. It provides recommended wiring diagrams and information on the measurements.
