Current transformer is more commonly used in the power industry, the purpose is to ensure the safe use of electricity. Anhui Amorphousbus E-business Co.,Ltd as a professional current transformers manufacturer, will tell you about some basic knowledge of current transformer.
There are some factors improves the current transformer accuracy. They are like burden, rating factor, load, external electromagnetic fields, temperature and physical Current Transformer configuration. Here, the factor of burden is given below.
The Rating factor of a Current Transformer which is dependent on ambient temperature, is a factor used to determine the absolute maximum measurable primary current by multiplying the full load of a Current Transformer. To maintain the accuracy in raising of the ambient temperature, the Current Transformer will have low capacity, and the rating factors of the Current Transformer s will range from 35 degrees Celsius and 55 degrees Celsius.
Another factor for the accuracy of Current Transformer is Physical Current Transformer configuration. If the conductors are not centered in circular or oval, the inaccuracy occurs in Current Transformer and this should be notified for correct accuracy.
Normally, the Current Transformer's are constructed in many ways like passing a single primary turn through a well-insulated toroidal core wrapped with many turns of wire. To measure waveforms of high frequency or pulsed currents within high pulsed power systems wideband current transformers are used specially. More info at amorphousbus.
