Definition of direction
for directional functions

e.g. P, Q, I
Measured quantity is
positive when flowing
towards the object
Set parameter
CTStarPoint
Correct Setting is
"ToObject"

Figure 2: Internal convention of the directionality in the IED
The correct setting of the primary CT direction
• CTStarPoint is set to FromObject or ToObject.
• Positive quantities flow towards the object.
• Direction is defined as Forward and looks towards the object.
The ratios of the main CTs and VTs must be known to use primary system
quantities for settings and calculation in the IED, The user has to set the rated
secondary and primary currents and voltages of the CTs and VTs to provide the
IED with this information.
The CT and VT ratio and the name on respective channel is done under Main
menu/Hardware/Analog modules in the Parameter Settings tool.
