SB-DN01 Power Quality Analyzer is running on the grid for monitoring and analysis of the quality of a dedicated portable products. Can provide electricity to run the harmonic analysis and power quality analysis, capable of large-scale electrical equipment in the process of starting or stopping the impact on the grid for the entire monitor that can run on the grid for long-term monitoring of data acquisition. Equipped with power quality data analysis software for measurement data uploaded to a computer for various analyzes. Technical parameters Technical Parameters Input impedance: 1MΩ, 20pF range, True RMS voltage 0-700V rms current: 1A, 10A, 100A, 1000A (select the corresponding probe) Frequency: 40Hz ~ 70Hz Accuracy: ± 0.5% harmonic measurement: 0 ~ 25 times harmonic inrush current: 2000A sharp peaks Voltage: 1000V recording time, 7.6 hours of memory capacity, 8M-bit Display: 320x240 graphic LCD Communication interface: RS232 Function Functions 1 Basic measurement: SB-DN01 Power Quality Analysis The basic instrument measurements show that the RMS voltage, RMS current, frequency and other basic parameters and measurement of voltage and current waveforms. Measuring the DC measurement source is displayed when an average value. 2 single-phase power measurement: SB-DN01 single-phase power measurements show apparent power, active power, reactive power, power factor. Measuring the DC measurement source is displayed when the DC power. 3-phase power measurements: three-phase power measurements show that the three-phase three-wire balanced load apparent power, active power, reactive power, power factor. 4 Harmonic measurements: voltage harmonic measurement into harmonic current harmonic harmonic measure, SB-DN01 major Showing 1 to 25 harmonics of the situation, including the sub-harmonic (or fundamental) frequency, True RMS harmonics, harmonic ratio (HR), total harmonic distortion (THD) and other parameters and harmonic cylindrical hoard. 5 Oscilloscope: The oscilloscope shows the voltage and current waveforms measured with operating, maintaining (or manually capture), the trigger (i.e. auto-capture) three operating states. 6 Starting measurements: Start measuring device for measuring the starting and stopping of large impact on power (mainly current), such shocks tend to persist for some time. While starting the stabilized current different from the previous measurement. It shows the process of starting the transient current and voltage values ??measured waveforms, and display the RMS measurement of current and voltage waveforms as well as the initial rms, current rms and their corresponding maximum rms voltage, current and voltage termination effective value (the DC source to be measured is an average value measured waveform display and various average). 7 Record: can the voltage, current, frequency, power, power factor, voltage harmonics and current harmonics and other electrical parameters of the detection of a long record of the electrical parameters obtained in record time maximum, average, minimum values, and the parameters of the recording time in the trend curve. 8 Data Analysis: SB-DN01 including fundamental analysis, single-phase power analysis, three-phase power analysis, harmonic analysis, start analysis, re-display the contents of the original measurement interface. 9 Data Upload: This feature allows the user to save the measurement data uploaded to the Pc machine to perform various analyzes. 10 System Upgrade: This feature allows the user to update the instrument using a microcomputer program.
