The Relay will be tested at loopback internal mode It should be noted that the minimum operating current is related, but not equal to, the Is1 SETTING Consider a single end fed fault with no load but fault current, I:|Idiff| = I |Ibias| = ½I Assuming |Ibias| < Is2, then, using the equations from section 2.1(from manual), the relay will operate if:|Idiff| > k1.| Ibias| + Is1 or I > k1.½I + Is1 or I> Is1 / (1 - 0.5 k1) The minimum operating current is therefore a function of the Is1 and k1 settings. Since k1 is Recommended to be set to 30%, the minimum operating current will be:Imin = 1.176 1s1
