The headroom at Node Y is calculated using the modified pre-existing background harmonic level. In the same way, the new harmonic headrooms are calculated and transferred to Node Y. As can be seen the limiting remote node is Node A. The multiplier M is 0.66 (for k=1, M=0.66). The harmonic limits for the harmonic under consideration for the second connection at Node Y are given in Table A. 7.
