maximum burden resistor across CT

[embedded.world@aol.com]

How to calcluate maximum burden resistance across CT.
I have CT with 60Hz frequency.

I want to generate 2.5V across it to measure it across adc.

How to calculate what could be maximum & minmum values of burden resistor for proper operation i.e without saturating the core.

sorry i don't have my crystal ball with me , therefore i can't guess the missing details accurately  to provide you a meaningful answer

Too large a resistance and the winding inductance reduces gain and causes phase shift.  The cutoff is: Rb <= 2*pi*F*Ls*/err, for err ~= 0.  Example: err = 0.01 (a 1% gain error).

This requires knowing the winding inductance, which is usually provided.  Sometimes, manufacturers will give a recommended maximum resistance, directly.
