66 - What is the difference between single phase harmonics & three phase harmonics?

3:43

• Differences in Harmonics: We discuss the difference between single phase and three phase harmonics, emphasizing that while both can have similar harmonic patterns, the specific frequencies involved and their effects on loads differ significantly. This is primarily due to the loads and their characteristic harmonics. • Characteristic Harmonics: We emphasized characteristic harmonics of three phase systems, particularly focusing on the NP ±1 pattern, where N is an integer and P is the number of pulses. This pattern is essential for identifying and analyzing the harmonic currents in three phase systems. • Single Phase System Harmonics: For single phase systems, you typically have all odd harmonics and like the three phase harmonics, their magnitudes decrease as the frequency increases. Eaton’s Harmonic Frequently Asked Question’s FAQs collection of videos hosted by Dan Carnovale can help individuals from all different levels of education understand what harmonics are and explain many different solutions for mitigating harmonics on an electrical power system. Dan Carnovale P.E. has decades of experience in power quality and harmonics and is a recognized electrical industry expert in power quality and power systems. He is the creator and director of Eaton’s Power Systems Experience Centers (PSEC) in Pittsburgh PA and Houston TX. The PSECs provide visitors live demonstrations of hands-on power quality and harmonic situations and solutions can be seen first-hand in the Power Quality Lab.
