Operation principle
SEMOD55028-5 v8
The direction of a current depends on the connection of the CT. The main CTs are typically star
(WYE) connected and can be connected with the Star (WYE) point towards the object or away from
the object. This information must be set in the IED.
The convention of the directionality is defined as follows:
•
Positive value of current or power means that the quantity has the direction into the object.
•
Negative value of current or power means that the quantity has the direction out from the
object.
For directional functions the directional conventions are defined as follows (see figure
•
Forward means the direction is into the object.
•
Reverse means the direction is out from the object.
