Usage Principle of Current Transformer

The wiring of the current transformer should follow the series principle: the primary winding should be connected in series with the circuit under test, while the secondary winding should be connected in series with all loadded instruments.

Selecting appropriate transformation ratio according to the measured current, otherwise the error will be larger. At the same time, one side of the secondary winding must be grounded to prevent the high voltage of the primary winding from entering the low voltage side of the secondary winding once the insulation is damaged, causing personal and equipment accidents.
