6.2.- THD
Note: This screen is not visible on the “slave” devices.
By pressing the key from the main screen, the THD display screen is accessed.
Figure 44: THD display.
It shows:
The voltage THD in each of the phases, L1, L2 and L3.
The current THD in the Mains in each of the phases, L1, L2 and L3.
The current THD in the Load in each of the phases, L1, L2 and L3.
Use the and keys to navigate through the different display screens.
6.3.- TDD
Note: This screen is not visible on the “slave” devices.
Note: This screen is only visible if the Line Current I
L
(A) has been set up on the IEEE519 configuration
screen, see “7.8.- IEEE519”.
Figure 45 shows the TDD, which is the ratio of the harmonic current to the nominal current in the line.
