  • Custom Power Devices like the Dynamic Voltage Restorer have been applied for voltage dip mitigation in the last years. These electronic equipments need fast and reliable voltage dip detection algorithms. Such
    detection methodologies must be able to detect a voltage dip as fast as
    possible and be immune to other types of perturbations. In this paper
    we address the problem of voltage dip estimation by different signal
    processing methods such as Fourier based algorithm and Wavelet
