Currente Transformer

 - Higher conversion accuracy

 - Measurements with increased safety

 - Supplied with factory calibration

Description

  Current Transformers, also known as CT's, are devices that allow measuring instruments to work properly without the need to have nominal currents according to the load current of the circuit to which they are connected. CT's transform, through the phenomenon of electromagnetic conversion, high currents, which circulate in their primary, into small secondary currents, according to a transformation ratio.

    In its simplest form, CT's have a primary, usually of one coil, and a secondary, in which the nominal current transformed is equal to 5A, in most cases. Thus, the measurement instruments are sized in small sizes, such as analog indicators with current coils consisting of small amounts of copper wire and digital instruments with a low power input resistance.

Applications

   Tanacas Current Transformer was developed to facilitate high current measurements (above 5 Aac), through a transformation ratio of currents above 5 Aac in the primary to a standardized current of 5 Aac in the secondary, for connection to Digital or Analog measurement instruments, and are used to supply devices that present low electrical resistance, such as ammeters, energy and power meters, etc.

   The Tanacas Current Transformer can be used in electric current measurements with greater safety, isolating the primary from the secondary measurement circuit, besides serving as an AC current sensor to avoid signals to the electronic control or alarm circuits.

     The Transformers can be supplied with a kit for rail mounting or others, according to the client's specification.
