Split core current transformers DP series:
The DP series of current transformers have been especially
designed to facilitate their installation in new or already
existing networks. Thanks to its split core they may be installed
without opening any cable or bus bar circuit.
The connection of conventional CTs usually requires the interruption
of the primary side circuit to pass cables or bus bars through
the transformer core or to connect such cables to the primary
terminals. The DP series transformers core may be easily opened
and they may be installed and connected without any supply
interruption, thus saving time and installation costs.
The main features of DP transformers are:
-Small size and easy mounting
-Wide inner window, allowing clamping of big cables or bus
bars
-Wide range of sizes to accomodate all the existing installations
-High accuracy and reliability
