Siemens SIPROTEC 5 User Manual

Identifying the Measuring Points
The measuring points can be assigned and established for example as in the Figure 1-3. The fault record or PQ
data acquisition requires, in addition to the selection of the measuring point, also a definition and establish-
ment of the evaluation criteria at the individual measuring points. There the monitoring of the Network
Quality is a combination of data acquisition techniques, which are classified according to purpose or use.
