NB:
The solution using one CT with the
current calculated via vectoral sum-
mation, results in an 0.5% reduction
in phase accuracy, of which current is
deducted vectorially.
NB:
The solution with 2 CT with the cur-
rent calculated via vectoral summa-
tion results in an 0.5% reduction in
phase accuracy, of which current is
deducted vectorially.
