9.3.1Open Delta System Installation Programming

A special switch is used to indicate that the electrical system being monitored is a Three- phase WYE or Three-Wire Open Delta System using the connection installation (see Chapter 3). The switch is located in GROUP 0, FUNCTION 3, Pack 1, Switch D.

This switch should be set to UP only if the electrical system is a Three-Wire Delta or Open Delta, using 2 PTs. Otherwise, the switch should be set to DOWN. Failure to select this switch results in Phase-to-Neutral readings, as well as incorrect power readings, with the 2PT connection.

Special Open Delta Connection Installation should be followed in the Installation and

Operation section (Chapter 3).
