** Burden resistance value yielding, 1 Volt per amp output with a single primary turn (Np = 1)
CTHT-17100-1000, -2000 and -5000 are preferred products.
** Burden resistance value yielding 1 volt per amp output with a single primary turn (Np=1).
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).
Note: All results shown assume a square waveform for the current, where Ton=0.5T. Other wave forms are supported to slightly higher peak currents.
