Introduction To Capacitors And Reactors Reactance includes inductive reactance and capacitive reactance, and reactor includes inductive reactance (inductor) and capacitive reactance (capacitor). Inductance has the function of blocking AC and blocking DC, that is, in the AC circuit, the characteristics of inductive reactance are used to pass low-frequency DC and block high-frequency AC. The capacit...
What is harmonic and how to manage it? Harmonics denote electrical quantities that possess frequencies which are integer multiples of the fundamental wave present in the current. This concept typically involves the Fourier series decomposition of periodic, non-sinusoidal electrical quantities. In this context, any electrical quantity with a frequency exceeding that of the fundamental wave, derived...
What is the reason for high neutral line current? Neutral current primarily arises due to two factors: three-phase unbalance and harmonic currents. Three-Phase Imbalance In a three-phase four-wire power distribution system, the ideal scenario entails an even distribution of loads across all three phases. This balance ensures that the vector sum of the three-phase currents is z...
