Illustration 4.38 CT’s installation does not measure capacitor
current.
For installations where the CT's connection point can be
moved,
is also possible. In some retrofit
applications summation CT is needed to reassure that the
capacitor current is not measured.
Summation CT can also be used to subtract two signals
from each other and so subtract the capacitor bank
corrected current from the total current
