Abstract
This paper proposes an effective Fault Detection Technique in distance relaying using discrete current samples. The original signal under fault consists of two parts namely, normal and disturbance part. The fault detection is easily achieved as the disturbance part of the signal produces an irregular shape compared to the shape produced from the normal part of the signal. By selecting suitable threshold value, the starting point of irregular part can be found. The proposed algorithm is so effective and easy when compared to other algorithms. Results are carried out in MATLAB/SIMULINK software.

Reduced Wire length-Based Low Power Performance Of Multibit Flip-Flop.  i-manager’s Journal on Circuits and Systems , 1(4), 22-26.  https://doi.org/10.26634/jcir.1.4.2593 Abstract Power reduction is a main parameter to design VLSI circuits. In this paper, to design a number of D-flip flop performing at the same time, the given clock signal is reduced using multi bit flip-flop. The multi bit flip flop is mainly used to improve the clock power for the given common clock signal and to reduce the switching power. This method is p...
