Home Fault Recorder & Power Quality Management


Solution package for Fault Recording and Power Quality Management.

SmartPQFRTM is a system that performs automatic collection, processing, and storing of power system data and records in normal operation conditions as well as fault & disturbance conditions. The system also provides reasons for equipment failure, oscillographic waveforms, status of equipment behaviour and other necessary information for power system analysis.


The detailed information of the power system displayed will enable operators to take corrective action necessary for given system issues and to analyse the quality of the power system to improve performance and reliability of any generation, transmission, and distribution systems.


The system provides all salient information on the power system to assist operators in isolation to determine failure cause and to process recovery, thus ensures the continuous operation of the power system.


Our solution complies with international standards of IEC, IEEE/ANSI as well as national standards and regulations of Vietnam Government and Electricity of Vietnam (EVN).
