Siemens SIPROTEC 5 User Manual

Function-Group Type Voltage/current 3-Phase
Overview
The Voltage-current 3-phase function group determines the measured values from the connected current
and voltage channels.
The current, power, voltage and frequency triggers operate in the function group Voltage-current 3-phase.
These trigger functions use one 3-phase current and voltage measuring point as the input.
The following function blocks operate in the function Current trigger (also see chapter 7.5.2.2 Structure of
the Function ):
•
I fund. Trig
•
I RMS Trig
•
I0 Trigger
•
I1 Trigger
•
I2 Trigger
The following function block operates in the function Frequency trigger (also see chapter 7.5.3.2 Structure of
the Function ):
•
Frq. Trigger
The following function blocks operate in the function Power trigger (also see chapter 7.5.4.2 Structure of the
Function):
•
P Sum Trig
•
Q Sum Trig
•
S Sum Trig
The following function blocks operate in the function Voltage trigger (also see chapter 7.5.1.2 Structure of
the Function ):
•
V Fund. Trig
•
V RMS Trig
•
V0 Trigger
•
V1 Trigger
•
V2 Trigger
The following function blocks work in the Recorder routing VI function:
•
PQ 10/12cyc fV
•
PQ trend fV
•
PQ flicker
•
Routing f
•
Routing I
•
Routing power
•
Routing V

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 values, trigger and recorder routing func-
tions) are not available.
