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.
The nominal operating data under P.System Data 2 should be set to the same
values at all ends of the protected object. This ensures uniform measured values dis-
played during commissioning and operation and sent to a central computer station.
2.1.4.1 Setting Notes
Nominal Values of
Protected Lines
The statements under this margin heading refer to protected lines (cables or overhead
lines) if no power transformer is situated within the protected zone, i.e. to models
without transformer option or if address 143 TRANSFORMER has been set to NO (see
Section 2.1.1.3).
With address 1103 FullScaleVolt. you inform the device of the primary nominal
voltage (phase-to-phase) of the equipment to be protected (if voltages are applied).
This setting influences the displays of the operational measured values in %.
The primary nominal current (address 1104 FullScaleCurr.) is that of the protect-
ed object. For cables the thermal continuous current-loading capacity can be selected.
For overhead lines the nominal current is usually not defined; set the nominal current
of the current transformers (as set in address 205 CT PRIMARY, Section 2.1.2.1). If
