| 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 |
