The CT passes directly through the meter without any physical termination on the meter.
This insures that the meter cannot be a point of failure on the CT circuit. This is preferable
for utility users when sharing relay class CTs. No Burden is added to the secondary CT
circuit.
Method 2: Current "Gills".
This unit additionally provides ultra-rugged Termination Pass Through Bars that allow CT
leads to be terminated on the meter. This, too, eliminates any possible point of failure at
the meter. This is a preferred technique for insuring that relay class CT integrity is not
compromised (the CT will not open in a fault condition).
