1250/5A Class 1.0 High Accuracy Split Core Current Transformer with CE Approval

Description :

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 

Selection of the Current Transformer

To select the current transformer correctly, the following points should be clarified:

- The application (for measuring or protection).

- The features of the working environment (Indoor or outdoor, operating temperature, air humidity etc….).

- Operation voltage and frequency.

- Range of the primary current (maximum and minimum of the current to be measured).

- Dimension of the cable or Bus bar.

- Data of the overload.

- Short circuit current.

- Specification of the measuring device associated with the current transformer (Accuracy, rated current, consumption etc…).

- The diameter and length of the cable, the cable which is used to connect the current transformer and associated measuring device.
