Note: In TEST 2 and TEST 3 for 51 and 51G, fault current will be injected directly to
check the theoretical tripping time. Take into account this time is calculated through an
equation and this time depends on the injected current, so doing a ramp is possible but
the theoretical tripping time will not be checked.
