Power Trigger
Overview of Functions
Power triggers start for the group triggers with exceeding or dropping below the set limiting values (level and
gradient trigger) in the fast-scan and slow-scan recorders. It is triggered on active power, reactive power,
apparent power, and power swing.
Structure of the Function
The Power trigger function is found in the 3-phase voltage/current function group, which is connected with
a 3-phase voltage and a 3-phase current measuring point.
The structure of the Power trigger function is shown in the following figure:
