Primary values
Settings/General Settings/Power System/Primary Values
Displays the system frequency.
9.2.1.4
Three phase analog group
Settings/General Settings/Power System/3PhAnalogGroup
Here, settings for the Fourier filters, the minimum system voltage required to measure
frequency, the item designation of CTs or VTs, and the system voltage are set. These
settings are required by the preprocessing blocks and are usually only adjusted during
the initial engineering phase.
9.2.1.5
Three phase analog summation group
Settings/GeneralSettings/Power System/3PhAnalogSumGroup
Here is where the settings for the summation block are done. The summation type,
fourier filter reference frequency, minimum voltage for frequency measurement and
the system voltage are some of the parameters that can be set here.
9.2.2
Communication
9.2.2.1
Overview
The parameter settings for communications are found under General Settings
\Communications. Communication settings cover network interfaces, protocol,
remote communication and reception of interlocking information.
9.2.2.2
TCP-IP
Settings/General settings/Communication/TCP-IP configuration/Front port
The IP Address and IP mask for the ethernet port on the front panel of the IED are
set here. These are generally used when connecting a PC directly to the IED.
Remember that this is a static IP address and that the appropriate network settings
must also be made in the PC.
Settings/General settings/Communication/TCP-IP configuration/Rear OEM-
Port AB
The IP address, IP mask and Link for the Optical Ethernet card at the rear of the IED
are set here.
Settings/General settings/Communication/TCP-IP configuration/Rear OEM-
Port CD
The same as the above but with different IP address if a second port is used.
