Load Values screens for single phase system:
There are only two versions of Load Values screens:
Load Values screen
* P44
Load Values Primary screen
* P69
Primary screen shows primary values which depend on CT and VT ratios defined for actual meter.
5.1.2 Actual Values
Actual Values screens show actual measured and calculated values of load point when other
combination than one current and one voltage measurement sensors are used.
Device shows measured and calculated values of Current (
CT ) and Voltage ( VT ) Transformers.
In case of connection of one measuring sensor device shows:

basic quantities (depends on used sensor)

Transmission Ratio r
Lx/L1

Transmission Error er
Lx/L1

Phase Error
φ
Lx/L1
Left values are comparison of values in phases L2 and L1 and right values in phases L3 and L1.
In case of connection of two measurement sensors device shows:

basic quantities (depends on used sensors)

Transmission Ratio r
B/A

Transmission Error er
B/A

Phase Error
φ
B/A
Showed values in each phase are comparison of values in Input A and Input B.
Transmission Error is calculated as comparison of measured Transmission Ratio ( r
Lx/L1
or r
B/A
) and
nominal Transmission Ratio ( r
nom
).
Content of Actual Values screens depends on connected measuring accessories.
