58 - Can you change an existing PF correction capacitor into a harmonic filter?

5:01

• Power Factor Correction Capacitors: A harmonic filter is simply a reactor and a capacitor in series but it’s not practical or recommended to change an existing capacitor into a harmonic filter because of voltage rise that can damage the capacitor. • Harmonic Filters: We discuss the creation of harmonic filters, focusing on the selection of tuning points to reduce power system harmonics emphasizing the importance of understanding the voltage rise across capacitors and the need to derate capacitors in terms of voltage when designing harmonic filters. • Power Factor Penalties: The discussion highlighted the primary motivation behind installing power factor correction or harmonic filters, which is to avoid power factor penalties on bills or to relieve the system's capacity. This underscores the economic and operational benefits of proper power factor and harmonic management. • Filter Design Considerations: We cover some of the specifics of designing filters, including selecting capacitors based on power factor requirements and tuning reactors to certain frequencies stressing the importance of ensuring both components can handle overvoltage and have the appropriate current ratings.
