ments of single phase power value cannot be duly calculated, and therefore, its value will be zero. Measurement for single
phase power value only will be provided when Wye connection is selected or when Delta connection and VN as Auxiliary
Voltage is selected in General Settings main menu. For the three-phase power value, the system uses the ARON method,
or two-wattmeters method.
6.3.1.4 ENERGY
Actual> Metering > Primary Values > Energy
Energy is only given in three phase primary values
Table 6–39: ENERGY PRIMARY VALUES
When the energy counters reach the value (2ˆ 31)/1000 (approximately 2147 MVArh and MWh) all the values are set to
zero and starts counting again.
