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.Ir=Maximum input current to be linearly sensed
5.VmaxRMS=Maximum voltage (saturation) CT will develop
6.Te=Effective turns ratio including losses
