The phase angles are listed separately in Table 2-14. The reference value for 3-phase objects is the current
Ι
L1M1
(current in phase L1 at measuring location M1), which has thus a phase angle = 0°. With 1-phase busbar
protection, the current Ι
1
has the phase angle 0°, i.e. it is the reference value.
Depending on the device’s order number, connection type, topology and protection functions configured, only
a part of the phase angles listed there is available.
Phase angles are indicated in degrees. Since further processing of such values (in CFC or when transmitted
through serial interfaces) requires values without dimension, arbitrary references have been chosen, which
are contained in Table 2-14 in the column “% Conversion”.
