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

Mechanical Specifications
Advantages
Good insulation performance and beautiful appearance. It has the characteristics of high sensitivity, good linearity, reliable operation and convenient installation. Its performance is better than the general zero-sequence current transformer, which is more widely used. It not only adapts to electromagnetic relay protection, but also adapts to electronic and microcomputer protection devices. Users can effectively ground or neutral according to the operation mode of the system. For the difference of non-effective grounding, select the appropriate zero-sequence current transformer.
QC
Liou has a strict quality control system. From materials to finished products. We conducted an inductive test on each core. Then choose the right core to make the transformer. Then we conducted DC, current, and high voltage tests. After approval, we check the appearance and parameters of the inspection and package the goods.
