| 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 |
