Three Phase DC Immune Current Transformer
The Three Phase DC Immune Current Transformer (CT) is a cutting-edge device designed to measure three-phase alternating current (AC) while effectively rejecting any direct current (DC) and external magnetic interference. This capability makes it ideal for complex power systems where AC and DC coexist, such as renewable energy installations and industrial applications. By utilizing advanced materials and design techniques, the Three Phase DC Immune CT ensures precise current measurements, enhancing system efficiency and reliability. Its robust anti-magnetic features provide further protection against external disturbances, making it a critical component for accurate monitoring and control in demanding electrical environments.

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
