High-def scopes from Teledyne LeCroy handle three-phase power analysis

A three-phase power analysis software package brings single-phase and three-phase static and dynamic power analysis to the HDO8000A, HDO6000A and WavePro HD 12-bit High Definition oscilloscopes from Teledyne LeCroy. With the 3-Phase Power Analysis software package, research and development engineers can now use Teledyne LeCroy’s 12-bit-resolution oscilloscopes to better understand complex power conversion system and control behaviors and hasten power conversion system-design refinements.

The rapidly growing power-conversion market now extends into applications requiring complex dynamic power analysis during time periods as short as a single device-switching cycle. Conventional power-analyzer instruments cannot perform dynamic power analysis and are limited to long power-period (e.g. 5 Hz to 500 Hz) analysis. Teledyne LeCroy’s 3-Phase Power Analysis software package now enables more thorough power-conversation system evaluations and provides deep insight into complex dynamic system behaviors in applications including dc-dc power supplies, hybrid/electric vehicles, solar PV and grid-tied inverters, welding equipment, uninterruptible power supplies and HVAC systems.

Capabilities include:
Numeric measurement table to display mean value “static” power behaviors
Per-cycle waveforms of “dynamic” power enables the correlation of complex power conversion system behaviors to other control or power system waveforms to debug drive system problems
Zoom+Gate mode for time-correlated, instantaneous understanding of dynamic power behaviors, and complete correlation to control system and other behaviors
Harmonic order calculations with tabular and spectral displays and THD measurements (available in optional Harmonics software package)
Support for two-wattmeter method to make accurate 3-phase power measurements using just two voltage and two current signals.

The 3-Phase Power Analysis software package is priced at $3,500. The ancillary Harmonics software add-on is priced at $1,545.
