A new method for detection of CT saturation is presented in this paper. The presented algorithm applies a new, innovative methodology mapping first order derivative of phase current signals into coordinates of a 3D vector. The comparison of proposed algorithm with standard one based on secondary current signal's second derivative is conducted and some of simulation results are presented to show the proposed algorithm effectiveness.
