Analysis of Electric Energy Supply Quality

The more applied the electronic instruments of measurement, the more important the quality of electrical power supply is. Quality of electrical power supply does directly affects the accuracy of measurements and results of scientific research. There are many parameters of measurement, which include deviation of voltages, deviation of frequencies, creation of unnormal harmonic disturbance in public power supply network, ets. For better monitor of electrical power supply and raising the accuracy of measurements, the related parameters are tested and final results are analysed.
