The PQE Digital Fault Recorder (DFR) is a fully featured Phasor Measurement Unit embedded with PQE state-of-the-art technology. The DFR  is a distributed multi-functional data acquisition device that continuously records all waveform signals at sampling rate of 1,024 samples per cycle. The continuous waveform recording makes the  DFR ideal for monitoring, protecting , operating, power quality, synchro phasors and load profiles. The DFR modular design allows to expend the system to almost any application in order to offer a cost effective performance. When coupled with PQE Power Quality Anaysis Software - a multi-vendors support power management software- the DFR provides a powerful platform for acquisition, analysis and report of data from power system substations.
