A new algorithm for estimating parameters of the fundamental component of a secondary current deformed due to CT saturation is presented in the paper. The algorithm is developed in an innovative 3D methodology where the samples of phase currents are considered as components of a 3D vector. The proposed algorithm can properly simultaneously remove the aperiodic components and distortions caused by...
A new method for detection occurrences of CT saturation is presented in this paper. The presented algorithm applies only first order derivatives of signals which is possible it has been designed in a new innovative methodology in which phase current signals are considered as coordinates of a 3D vector. The proposed algorithm is compared with standard one applying secondary current signal combined...
