1 Introduction
The Service report menu lets you display information about the:
• Operation conditions for protected objects in the power systems
•Terminal
The amount of available information depends on the number of basic and
optional functions in a specific REx 5xx terminal.
The way in which different subgroup information is displayed on the
MMI depends on if the corresponding function is in the terminal. These
subgroups describe possible types of information:
• Mean values
• Differential values (only if the line differential protection function is
included in the terminal)
• Phasors
• Synchronising values
• Logical signals
• Different I/O units
• Counters within the auto-reclosing function
• Communication channel (only if the line differential protection func-
tion is included in the terminal)
• Directionality
• Disturbance report
•Active group
•Internal time

2.1 Mean values MMI branch:
Service Report
Mean Values
Line-distance protection terminals display the mean values of measured
current, voltage, active and reactive power and frequency. That is related
to phase L1, L2 and L3. The amount of this information in other types of
terminals depends on the built-in optional functions.
