single line to ground fault detection on matlab in matlab

Here is an example code to perform single line to ground fault detection on MATLAB:

main.m
% Define the current values for each phase
Ia = [1, 2, 3, 4, 5];
Ib = [2, 4, 6, 8, 10];
Ic = [3, 6, 9, 12, 15];

% Calculate the ground fault current
Ig = sqrt(Ia.^2 + Ib.^2 + Ic.^2);

% Set the threshold for ground fault detection
threshold = 5;

% Detect ground faults
ground_faults = find(Ig > threshold);

% Display the results
if isempty(ground_faults)
    disp('No ground faults detected');
else
    disp(['Ground faults detected at indices: ', num2str(ground_faults)]);
end

In this code, we assume that the current values for each phase (Ia, Ib, and Ic) are already defined. The code calculates the ground fault current (Ig) by summing the squares of the current values for each phase and taking the square root. It then compares the calculated ground fault current to a threshold value (threshold) to detect ground faults. If any ground faults are detected, their indices are displayed; otherwise, a message indicating no ground faults are detected is displayed.

Feel free to adjust the values of Ia, Ib, Ic, and the threshold to fit your requirements.

Note: This is a simplified example and may not be suitable for all scenarios. Consider consulting with an electrical engineer for more accurate fault detection techniques.
