Answer Posted / munwar ali bhand
The CT saturates when we exceed load on CT greater than its VA burden capacity either in case of fault or during testing or normal operation. VA burden depends upon core material of CT used and depends upon B-H curve of the material. These ferromagnetic materials used have ability if they are over excited than they will loose their normal operation properties. in this why if we put more load than its VA capacity of CT than CT will saturate. means that it will not give you accurate results.

Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line; i.e. the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The maximum value of n1(P) over all configurations P of 19 points in the plane is 18
