Current transformers are electrical equipment that converts primary currents to proportional secondary currents that are appropriate to the connected measuring instruments.
Current transformers have a primary winding to which the current to be measured is fed. Measuring instruments are connected to a secondary winding. Current transformers are used for measuring and protecting applications.
It is recommended to apply current transformers for currents of 40 A or higher.
