Power System Data 2
The general protection data (P.System Data 2) include settings associated with all functions rather than a
specific protection, monitoring or control function. In contrast to the P.System Data 1 as discussed before,
these can be changed over with the setting groups and can be configured via the operator panel of the device.
2.1.5.1 Setting Notes
Rating of the Protected Object
The rated primary voltage (phase-to-phase) and rated primary current (phases) of the protected equipment are
entered in the address 1103 FullScaleVolt. and 1104 FullScaleCurr.. These settings are required for
indication of operationalmeasured values in percent. If these rated values match the primary VT's and CT's,
they correspond to the settings in address 203 and 205 (Subsection 2.1.3.1).
General line data
The directional values (power, power factor, work and related min., max., mean and setpoint values), calculated
in the operational measured values, are usually defined with positive direction towards the protected object.
This requires that the connection polarity for the entire device was configured accordingly in the Power System
Data 1 (compare also „Polarity of Current Transformers", address 201). But it is also possible to reverse the
direction for the outputs without having to change the transformer connections e.g. so that the active power
flow from the line to the busbar is indicated in the positive sense. Set under address 1107 P,Q sign the option
reversed. If the setting is not reversed (default), the positive direction for energy flow from busbar to line
are evaluated as being positive.
