Harmonic Analysis

The Radian RS-933 Power & Energy Automated Calibration System is one of the most powerful harmonics analysis tools in the world. The RS-933 allows the user to create arbitrary waveforms with harmonic components up to the 65th harmonic order. Using a simple waveform creation screen, harmonic amplitudes and relative phase angles are entered in any combination. Immediate visual feedback is given showing the nature of the waveform being created. Waveforms can be saved and later applied to either the voltage and/or current axis. The RS-933 then sources these waveforms to appropriately connected devices. The energy measurement accuracy of the RS-933 is better than +/-0.005% traceable to NIST with fundamental waveforms. This functionality allows for detailed harmonics response analysis of revenue meters and power quality instruments.

Radian RD-Standards offer harmonics analysis as an optional feature. Any RD standard can be configured to measure and display up to the 65th harmonic for both voltage and current signals. All standards purchased with the harmonics analysis option come with PC based RR-PCSuite software for graphically viewing and logging harmonics data.
