Introduction

 

The DC Immune Current Transformer (CT) is a specialized device designed to accurately measure alternating current (AC) without being affected by DC components. This unique capability is crucial in applications where both AC and DC coexist, such as in renewable energy systems, electric vehicles, and industrial automation. The DC Immune CT utilizes advanced magnetic core materials and innovative design techniques to ensure high accuracy and reliability, making it an essential tool for monitoring and controlling electrical systems.

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.R_L=Terminating resistance. Varying terminating resistance increases or decreases output Voltage /Ampers according to following

equation R_L=Vout*Nsec/Ipri
