Figure 161: Single line diagram for transformer application
In order to measure the active and reactive power as indicated in figure
161, it is
necessary to do the following:
1. Set correctly all CT and VT and phase angle reference channel PhaseAngleRef
data using PCM600 for analog input channels
2.
Connect, in PCM600, measurement function to LV side CT & VT inputs
3. Set the setting parameters for relevant Measurement function as shown in table
40.
The power P&Q measurement is needed towards busbar (not towards IED, as
default). Proper inversion of current should be done in SMAI block for the current
channels in order to get correct direction of P&Q. Note that, in such case this
SMAI block shall only be used for the measurement functions.
