A series of measured values and the values derived from them are available for on-
site retrieval or for data transfer.
Precondition for a correct display of primary and percentage values is the complete
and correct entry of the nominal values of the instrument transformers and the power
system.
Depending on the ordering code, connection type to the device and the configured
protection function, only some of the listed operational measured values in Table 2-14
may be available. Only one of the current values I
one which is connected to the current measuring input I
only be measured if the phase-to-earth voltage inputs are connected. The displace-

If the device features a synchronism and voltage check function, and provided that
these features have been set to  during configuration of the scope of the device
(address (QDEOHG), and that the parameter 8 WUDQVIRUPHU (address ) has
been set to 8V\QF WUDQVI, the characteristic values (voltages, frequencies, differ-
ences) can be read out.
The power and operating values upon delivery are set such that power in line direction
is positive. Active components in line direction and inductive reactive components in
line direction are also positive. The same applies for the power factor cosϕ. It is occa-
sionally desired to define the power draw from the line (e.g. as seen from the consum-
