ISQ ascertains the quality of electrical energy, identifying nonconformities with the standard NP EN 50160, and analyses all the recorded parameters. Quality of electrical energy Analysis and monitoring of the quality of the electrical energy, according to the standard NP EN 50160, using Class A precision equipment  Monitoring disturbances in electrical grids Measurement and record of the total harmonic distortion of voltage and current. Registration of the waveform. Ascertainment of the nature and origin of harmonic distortions Energy and power Measuring and recording of all parameters of energy and electrical power (voltage, current, starting current, power factor, energy consumed, etc.). Possibility of monitoring for extended periods.
