If only Voltage Preprocessing (UTVTR) is available, or if both Voltage Preprocessing (UTVTR) and Current Preprocessing (ILTCTR) are available, the voltage angle is taken as a reference for angle calculation.
If only Current Preprocessing (ILTCTR) is available, the current angle is taken as a reference for angle calculation.
In measurement functions CMMXU, VMMXU, RESVMMXU and RESCMMXU, the execution order of UTVTR should be set to a lower value (O:1 or lower execution number) for the voltage angle to be taken as reference. If lower execution order is not set, voltage angle from the previous execution round is taken as a reference for the measurement angle calculation. The execution order can be set as illustrated in Figure 1.
