1) Three Wire Direct Connection Using 2 CTs (2-element)
This connection can be applied to systems with line-to-line voltage up to 660V. The
three line voltages are taken at terminals 2, 5 and 8 as shown in Figure 2-5.
Figure 2-5 3-wire Direct Connection Using 2 CTs (2-element) WIRING MODE 3DIR
Readings represent line-to-line voltages. The two line currents are monitored via
two CTs. The third current is calculated based on the two measured currents.
