ADVANCED FEATURES
OXYGEN’s advanced power option gives you detailed insights into your DUT by analyzing frequency domain and more. In addition, it is the perfect add-on for inverter designers as it automatically calculates electrical and mechanical efficiency and seamlessly provides a d/Q analysis. It is also the perfect choice for engineers in the PV industry, because voltage fluctuation and flicker analysis is also included.
- Analysis of (intermediate) harmonics (IEC 61000-4-7)
- High-frequency components
- Supraharmonics
- Voltage fluctuations(IEC 61000-4-15)
- Flicker emissions (IEC 61400-21)
- D/Q analysis
- Mechanical power analysis
- Efficiency analysis & online efficiency mapping
EXPERT FEATURES
If you are working with renewable energy sources, have a look into OXYGEN’s expert power option as it features calculations in accordance with IEC 61400-21 and FGW TR3
- Rolling calculations meeting FGW-TG3 requirements
- Adaptable thresholds and update rates supported for individual analyses
Harmonics and Flicker validation
OXYGEN’s universal power instrument can not only be used for visualizing your measurement data but also be used to validate your harmonics and flicker results and report if predefined limits have been exceeded. Pass/fail limits can be freely defined by the user depending on the required standard. The results are displayed in a structured overview that can be directly used for reporting.
This powerful feature can be used online while the measurement is running or offline when analyzing the measurement data.
Harmonics validation:
Evaluation of Harmonics and Interharmonics of voltage, current and power
Flicker validation:
Evaluation of dc, dmax, td, Pst and Plt for the Plt aggregation time
