Abstract

The quality analyzer grids is a portable electronic device that helps troubleshoot problems in power distribution systems quickly, securely and detailed. This portable instrument has a design that uses advanced technology for integrated circuits and digital signal processors surface mount components professional level, a user interface easy to use and housing suitable for the use of the tool. This instrument was developed to measure electrical signals of voltage and current in real time using 4 + test leads alligator clips and 3 HT 4003 AC transducers clamps connected to the back of the unit. This prototype allows the display of curves and numerical data of 3 phase voltages, three line voltages, 3 currents, the phase shift between the signals of voltage and current signals between vs. voltage signals, the calculation of active power, reactive, complex and power factor, harmonics measurement and calculation of the THD of each of the signals, and the frequency measurement for the reference signals.
