3.5.5 Naming convention to identify protection relays
The protection relay name must be unique within the planned network. A default name is
applied if it is not specified by the client and it is based on the reference designation system
of IEC 61346
– Substation 3 characters
– Voltage Level 1 character
• B > 420kV
• C < 380, 420> kV
• D < 220, 380) kV
• E < 110, 220) kV
• F < 60, 110) kV
• G < 45, 60) kV
• H < 30, 45) kV
• J < 20, 30) kV
• K < 10, 20) kV
• L < 6, 10) kV
• M < 1, 6) kV
• N < 1 kV

3.5.6 IP address allocation
The IP address is a number that identifies a network device. Each device connected to a net-
work must have a unique address. The default IP address range for a substation is: 172.16.X.X -
172.30.X.X. The IP addresses and IP masks are a specific feature of each device. In case of
device failure, the replacement device receives the same IP address. The IP address should be
structured in a way to reflect the physical plant layout according to IEC 61850-90-4.
