Voltage Sag Detection Based on Rectified Voltage Processing [PDF]
IEEE Transactions on Power Delivery, 2004 An algorithm for voltage sag detection based on rectified voltage processing is presented and its performances are evaluated by means of simulated and real voltage waveforms (recorded at some low-voltage busbars and measured on a scaled prototype of a voltage support system). The algorithm is intended to detect voltage sag occurrence and to trigger the
