When u are adding a custom library for a relay (from the "library" menu at the top) in ETAP 7.0, at the "relay library: model" window , in the "model info" section,,,, there is a parameter called "current setting" and the value of which is: 0.2, 1, 2, 5, 2/5, 1/2, 1/5, 1/3/5, 0.1/1/5, 0.2/1/5, 0.03/0.2/1/5, etc My question is what is its meaning? is it the relay amps of the input CT connected to the relay or is it the currents which the relay can read as an input? so that if i set the current setting of a relay to, for example: 0.03/0.2/1/5, does it mean that the relay can only receive 0.03, 0.2, 1 or 5 ampere as an input? I'm a bit confused about this
