Connecting a current transformer
The connections of the primary winding are designated as
"K" and "L" or "P1" and "P2". The connections of the
secondary winding are designated as "k" and "l" or "s1" and
"s2". Pole the cables so that the power flows from "K" to "L".

Each calibrated current transformer is provided with a corresponding calibration certificate.
The calibration process involves additional costs, which are specified in accordance with the national table of fees.
These depend on the maximum rated input current of the current transformer.
