EP 26 - Power Line Analysis and Power Factor

Today I perform a demonstration of how capacitive, resistive, and inductive loads interact with one another. I show how current leads voltage when a capacitive load is applied to the circuit, and I show how the opposite effect occurs when an inductive load is applied. In addition to this, I demonstrate how adding a capacitor in parallel to a highly inductive motor load actually serves to decrease the current (though not the real power) drawn by the system. In order to perform these experiments, I also demonstrate how to use a series-connected resistor to perform power line analysis on any power load, using the two channels of an oscilloscope. I conclude this video with a brief overview of phasor diagrams, and a more formal mathematical representation of power factor. I also highlight the importance of power factor correction in industrial applications. Thanks for watching!
