Quick Summary

A delta connection is a way to link electrical devices to a three-phase circuit. In this setup, the three points of a delta shape are connected to the three wires of the power supply. This is also known as a mesh connection. It's contrasted with other types of connections like star connections or open-delta connections. An open-delta connection is a less permanent or emergency setup where one of the three transformers is removed, and its load is handled by the remaining two transformers. This is sometimes called a V-connection.12
