When Plotting relay current curves using log paper, I understand that all curves should be plotted on a common base voltage (converting currents accordingly) and the curves can be cut at the maximum fault current level that the device is likely to see (corrected to the base current). What I would like to know is where the curves should be started, e.g. at what current value should I start the curve?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks
