Averaging of signals and measurements in electric power testing
In electric power testing, many signals are measured in several domains (e.g., electrical, mechanical, sound&vibration). In most cases, measured signals are processed to get a new signal, which gives more information about the initial signal (e.g., the power consumed and generated over a single revolution of a machine). In addition, processed signals can be averaged to, for example, remove fluctuation due to uncontrollable conditions.
In this free webinar, HBK’s Tom Kevenaar explains how averaging could and sometimes should be carried out to obtain the best and most meaningful results. Both the averaging of equidistant sampled signals and non-equidistant processed signals are discussed, as well as some guidelines for choosing an averaging approach in an electric power test setup.
Key topics and takeaways:
- Discover how to average equidistant and non-equidistant sampled signals
- Find out what it means if we average a processed signal
- Learn how to choose an averaging approach
