Introduction

The DC Immune Current Transformer (CT) is a specialized device designed primarily for the detection of alternating current (AC) while remaining immune to the effects of direct current (DC). This functionality is particularly important in applications where AC signals need to be measured without interference from any DC components. Utilizing advanced magnetic core materials and innovative design, the DC Immune CT ensures high accuracy and reliability in AC current measurement, making it an essential tool for effective monitoring and control in various 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
