To match your monitoring circuitry to a specific CT, you need to know the CT characteristics in relationship to input current, turn ratio, and frequency range. The Rb referenced in the curves below is defined as Rb = 1 Volt/Is, the value which will yield one volt per amp output, where Is=(Np/Ns) Ip. To assist with choosing Rb, see graphs below. Lower or higher Rb values can be used for your specific requirements. Contact a Precision engineer for assistance (See buttons below).
