Complete System DebugAcquire power and control system signals and perform 3-phase power analysis of the power section waveforms. Correlation of system behaviors to embedded control loop signals enables debug and analysis of all aspects of a 3-phase electrical system.

Numerics Measurement TableVarious voltage, current, power (real, apparent, and reactive), phase angle/power factor, and efficiency parameters are calculated on acquired voltage and current waveforms and displayed in a table. The table is displayed along with the acquisition waveforms.

Zoom+Gate Dynamic AnalysisCapture long acquisitions and Zoom+Gate with instant table value updates and views of dynamic 3-phase power performance.

3-phase Two-wattmeter Method SupportTwo-wattmeter measurement method is supported, allowing 3-phase power measurements to be made using two voltage and two current signals. Therefore, 3-phase measurements can be made using 4 channels instead of 6.

Teledyne LeCroy’s 3-Phase Power Analysis software package provides complete 3-phase electrical power analysis. Static power results are in a convenient, configurable Numeric table, and dynamic power results are displayed as per-cycle Waveforms. Zoom+Gate mode provides ability to understand and isolate dynamic behaviors. All aspects of system debug and validation on any building block (AC-AC, AC-DC, DC-DC, DC-AC) of a Power Conversion system can now be easily performed.

6. Zoom+Gate Mode Take a single long acquisition of a dynamic event, and with the press of one button, zoom through the waveforms and gate the measurement results to the zoomed area. Change the zoom position and the measurement tables and per-cycle “synthesized” Waveforms update instantly. Gain faster understanding of dynamic system behaviors.

7. Dynamic Power Waveform Displays Simply touch a measurement and a per-cycle “synthesized” Waveform is created showing the change in that measurement over time

8. Per-cycle “Synthesized” Waveforms The Per-cycle waveform updates to the Zoom+Gate window when enabled.

9. Cursors Place a cursor on any waveform and get an instantaneous reading of system behavior

BEYOND “NUMBERS” - MORE INFORMATION

Like a power analyzer, a user-configurable table is provided for display of a selection of power (real, apparent, reactive), power factor, phase angle, efficiency, voltage, or current parameters. Up to 120 values total may be displayed in 10 rows and 12 columns for any selection of input or output individual phase or total 3-phase, or DC bus/link values.

The numeric values displayed are mean values from a statistical data set that is calculated on a “per-cycle” basis using a user-defined synchronization source signal. This display corresponds to what is normally provided by a dedi-cated power analyzer instrument.

Per-cycle “Synthesized” WaveformsA single averaged value “hides” dynamic behaviors. Simply “touch” the value in the Numerics table and a detailed per-cycle Waveform will be created from the complete per-cycle measurement set and then automatically displayed time-correlated to the original acquisition. Statistical values (min, max, number, etc.) can also be displayed. Use this advanced capability to correlate complex power conversion system behaviors to other control or power system waveforms, and to debug drive system problems. This capability is not provided in any Power Analyzer instrument.

Zoom+Gate ModeEnable Zoom+Gate mode to create zooms of all channel acquisitions and gate the Numerics and Statistics mea-surement tables to the zoomed area. Per-cycle displayed Waveforms will be zoomed and time-correlated to the other Zoomed waveforms. Change the zoom location and size and the data will instantly update. Scroll quickly through your measurement set to gain fast and deep insight into dynamic power conversion system behavior.

3-phase power measurements can be made using either the three-wattmeter or two-wattmeter method. An 8 channel oscilloscope allows direct measurement of three voltage and three current signals (three-wattmeter method). Support is provided for a Line-Line to Line-Neutral voltage conversion so as to allow intuitive line-line probing with per-phase line-neutral reported results.

A 4 channel oscilloscope can also make 3-phase power measurements using the two-wattmeter measurement method. This is done by measuring two voltage and two current signals.

On an 8 channel scope, two-wattmeter measurement support allows input/output efficiency measurements of the complete power conversion system to be performed (4 channels for input V & I measurement + 4 channels for output V & I measurement).
