Current Sensor Transformer used for high precision current measuring
Measuring the energy used is essential for various industrial applications and homes. The utility bills we pay are based on the energy measured by these meters. Industries also require energy measurement for the same reason, alongside monitoring and data acquisition. This enables them to understand how the equipment functions and whether the internal electrical processes behave as they should

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
