the date and time they were last updated. The minimum/maximum values can be reset
via binary inputs or, in the delivery status of the device, also via the F4 function key.

gawatt hours primary or in kVARh, MVARh or GVARh primary, separately according to
the input (+) and output (–), or capacitive and inductive.
The calculation of the operational measured values is also executed during fault. The
values are updated at intervals of ≥ 0.3 s and ≤ 1 s.

Definition of Power Measurement
The 7UM61 uses the generator reference-arrow system. The power output is positive.
Figure 2-80
The following table shows the operating ranges for synchronous and asynchronous
machines. For this, parameter 1108 ACTIVE POWER is set to Generator. "Normal
condition" shows the power under normal operating conditions: + means that a posi-
tive power is displayed on the protective device, – means that the power is negative.
