High Precision current Transformer with primary bus bar
DC immune current sense transformers are used for sensing the AC currents where DC offsets also exist. The current sense transformers create a voltage when current flows. They are primarily made for sensing AC currents in a circuit so having a DC bias can distort the AC measurement. Some specialized alloys of magnetic materials are referenced as DC immune. DC immune means that they will not react or distort the AC measurement so there can be more accurate AC measurements even if there is a DC offset present.

Note:
1.Output voltage is proportional to the derivative(di/dt)of the input current based on the Rogowski Coil principle.
2.All current and voltages assumed to be sinusoidal waveforms at Fr, the constant rated frequency in Hz, measured as RMS value.
3.Accuracy class per IEC60044-1Table 11.
4.Ipri=Rated primary current.
5.Iout=Rated secondary current.
6.Iprimax=Sensed max primary current.
7.Loutmax=Sensed max secondary current.
8.RL=Terminating resistance. Varying terminating resistance increases or decreases output Voltage /Ampers according to following
equation RL=Vout*Nsec/Ipri
