Claim 5:
6. The method according to claim 1, wherein the restraining current for an M-terminal transmission system at time t is denoted I_(res,x) (t) and is defined as:

I_(res,x)(t)=((|I_(s,1,x)(t)|+|I_(s,2,x)(t)|+ . . . +|I_(s,M,x)(t)|))/M,, where I_(s,m,x) (t), with m ranging from 1 to M, represents instantaneous sent current at time t from terminal m along the transmission line for phase x, where x∈{A,B,C} for a 3-phase transmission system with phases A,B,C.
