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

Advantages

Suitable for all kinds of currents.

High cost performance, environmental protection and pollution.

Small size, high precision and good consistency.

Excellent ratio error and accuracy.

Detailed installation in different situations

When installing a current transformer, it is mainly evaluated according to the configuration of the equipment. Under normal circumstances, there are several different situations.

1. Install the current transformer directly on the metal frame, such as the structure of the busbar;

Second, if the busbar passes directly through the floor or the wall, the current transformer is fixed with the most basic bolts, or the angle frame is used to make the rectangular frame, and then the current transformer is directly fixed on the frame.

Third, the current transformer is installed directly in the complete power distribution cabinet. For the current transformer of this type of installation, in fact, we do not need to install the body, only the key inspection wiring can be used.
