Power grid parameter monitoring system

Task

Monitoring parameters of the three-phase supply network with the registration of the values and shape of the voltages and currents of each phase, as well as fixing the output beyond the permissible values for the amplitude and frequency or consumed currents

Equipment

Self-recording voltmeter Flash-Recorder-3 M6, USO8-AISO isolating amplifier board, current pliers

Solution

 Contact free connection with current clamps to the supply network to measure currents and contact connection via isolation amplifiers for measuring the voltages of each phase. The high sampling rate of the ADC allows you to measure the phases and register the waveform at each phase. The "Overshoot" software has been developed with a user-friendly interface in the of columns and a digital scoreboard, as well as continuous recording to a file when the amplitude, shape or frequency of signals exceed the limits set by a user
