DP Current Transformers

Dp-23

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

Split core current transformers MES series:

The MES series of current transformer have beautiful outline and Convenient for mounting in many ways. The most current transform need the special mounting and the MES series used the mounting of DIN typing With a lot of times. The protective cover for the terminal block used the switching device with Safety and quick.

PR Current Transformers

PR Series:

Protective current transformers are required to operate over a range of current many times the circuit rating and is frequently subjected to conditions greatly exceeding those which it would be subjected to as a measuring current transformer. When a current transformer is used to energize a protective relay, it must maintain its characteristic ratio up to some multiple of its rated current. This multiple, may be 5, 10, 20 or some even higher value and is know as the "Accuracy Limit Factor"(ALF). Therefore, the selection of Protective Current Transformers in relation to accuracy class and ALF require a close examination of relay characteristic and circuit conditions which includes the relay burden and the pilot wire lead burden.
