2) Three Wire Open Delta Connection Using 2 PTs, 2 CTs (2-element)
This configuration, shown in Figure 2-6, can be used with either 660V or 120V
input. Readings represent line-to-line voltages. The two line currents are measured
via 2 CTs; the third current [LINE 2(B)] is calculated based on the two measured
currents. The common taps of the PT secondaries are connected to terminal 11.
Note the connection between terminals 5 and 11.
