Inversion of Measured Power Values / Metered Values
The directional values (power, power factor, work and related min., max., mean and setpoint values), calculated
in the operational measured values, are usually defined a positive in the direction of the protected object. This
requires that the connection polarity for the entire device was configured accordingly in the P.System Data
1 (compare also "Polarity of the Current Transformers", address 201). But it is also possible to make different
settings for the "forward" direction" for the protection functions and the positive direction for the power etc., e.g.
to have the active power supply (from the line to the busbar) displayed positively. To do so, set address 1108
P,Q sign to reversed. If the setting is not reversed (default), the positive direction for the power etc.
corresponds to the "forward" direction for the protection functions. Section 4 provides a detailed list of the
values in question.
2.1.6.3 Settings
The table indicates region-specific default settings. Column C (configuration) indicates the corresponding sec-
ondary nominal current of the current transformer.
