What is the reason of resonance in power networks? Resonance in power networks occurs when the inductive and capacitive elements of the system interact in a way that amplifies specific frequencies, leading to excessive voltage or current oscillations. Here are the primary reasons for resonance in power networks: 1. Impedance Matching Resonant Frequency: Every electrical circuit has a natural reson...
