2.1.4 General Protection Data (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.
To ensure uniform conversion factors of measured values for WEB-Monitor and control centres, the setting of
all operational rated values of the parameter groups under P.System Data 2 should be identical.
2.1.4.1 Setting Notes
Rated values of protected lines
The information under this margin heading only apply if no power transformer is located within the protected
zone (device version without transformer option or address 143 TRANSFORMER set to NO, Section 2.1.1.3).
With address 1103 FullScaleVolt. you inform the device on the primary rated voltage (phase-to-phase) of
the equipment to be protected. This setting influences the displays of the operational measured values in %.
The primary rated current (address 1104 FullScaleCurr.) is that of the protected object. For cables the
thermal continuous current-loading capacity can be used as a basis. For overhead lines the nominal current is
usually not defined. Here it is advisable to select the rated current of the current transformers (as in address
205 CT PRIMARY, Section 2.1.2.1). If the current transformers have different rated currents at the ends of the
protected object, set the highest rated current value for all ends.
