Connection of CT current transformers in the three-phase
3.
device.
The voltage is read directly, while the current is measured via
the external current transformers.
The current transformers are already wired. They must be
installed on the cables of phases L1, L2 and L3, just after the
IGA, making the arrow match the direction that the current
follows in the installation when energy is fed into the network:
from the loads to the connection.
