Measurands and Recorder Routing Functions
Measurands
Properties of Measurands
With the SIPROTEC 5 device, various recording options are available for supervision and evaluation of the
power-system voltage quality. Measurands are measured or calculated in 3-phase systems.
To achieve the best power-quality supervision, the following tables contain recommendations on routing the
measurands in DIGSI 5.
Using Measurands
Function Description
The sampled values (SAV) are automatically routed to the Fast-scan recorder and cannot be changed by the
user. The measured values, on the other hand, are formed from the sampled values. You can route the meas-
ured values manually in Information routing.
NOTE
The Voltage-current 3-phase function group also works without an assigned voltage measuring point. In
this case the voltage, frequency and power functions (measured value, trigger and recorder routing func-
tions) are not available.
After you have instantiated the Recorder routing function and the desired function blocks, you can assign the
measured values to the individual recorders in the Information routing.
