Oscilloscope Coffee Break Webinar Series
Join Teledyne LeCroy for this 30-minute Oscilloscope Coffee Break Series to remind us how to get the most test and debug capability from our oscilloscopes. Grab your refreshment and spend a few minutes with us as we focus on a specific topic each month. Click here to access the entire series.
How Do I Make 3-phase Power Measurements with an Oscilloscope?
Instantaneous real power (in Watts) is simply voltage multiplied by current. But what if you want to calculate the average real power during one operational power cycle? How would apparent power (Volt-Amperes or VA), reactive power (Volt-Amperes reactive, or VAr), and other power quantities (power factor, phase angle, etc.) be calculated and how is this done in a three-phase system?
In this coffee break webinar we will provide the mathematical explanation of the power calculations used in power analyzers and oscilloscopes and how both instruments identify a power cycle during which to calculate values.
