One transformer is Dy1 and the other is Dy11
In this case there are already 60° phase shift between phase R
local end and the phase R of the remote end. Supposing you
have connected the T1000 PLUS to phase R in the remote end,
you have three possibilities on the local end:
If you measure something like 200 or 346 A, it means the two
T1000 PLUS are connected to a different phase reference. As
you may see, in this condition Phase B of one end correspond
to the phase R + 180° of the other end.
Switch SWT3 to the next position until you get the proper
values.
