Power Quality Monitoring
Power quality monitoring solutions from National Instruments combine rugged hardware for waveform measurements with flexible software capable of performing any power monitoring, power quality, or power metering analysis. You can perform measurements such as root-mean-square (RMS), power factor, frequency analysis (fast Fourier transform), and harmonic analysis in phase over multiple channels. With the NI LabVIEW graphical development environment and NI power monitoring systems, you can integrate hardware measurements with analysis and reduce development time. Simultaneous Sampling for Phase AlignmentIt is essential to measure the phase offset between the voltage and current waveforms to calculate real power and the power triangle. To measure this phase offset, you must acquire data at the same time on each channel to preserve the existing phase angle and not introduce additional phase offset from the instrumentation.
Isolation Technologies for a Safer and More Accurate MeasurementBy creating a physical separation in the measurement equipment, isolation increases accuracy, simplifies installation, and, more importantly, adds a safety factor to the system when working around high voltages. |
