Quality signal of IEC 61850 communication
11.3.7
Quality information and its attributes are defined in the IEC 61850. Table 11.3-6 shows that
the relations between the definitions in the standard and signals prepared in the IED. The
quality attributes are influenced by the errors and alarms occurred in the IED, and the degree
of those errors are standardized by settings 'Error level' (see Chapter
The quality information is also affected by the test mode executed in the IED (see Chapter
