R3 represents the starting limit on the R axis (detection sensitivity of resistive defaults
– The starting element for phase/earth can be superior to the phase/phase). If the
reverse zone has been disabled (Z4), there is still a no-trip zone (up to version A3.2 &
2.10) in the 4th quadrant below the R axis.
