Working Principle of AHF
AHF detects harmonics in real-time and generates counteracting current to eliminate harmonic distortion, ensuring power quality.
Eliminating Neutral Current with AHF
Neutral current occurs due to third-order harmonics and unbalanced loads, leading to excessive current flow through the neutral conductor. This can cause overheating, equipment damage, and inefficiency in the power system.
AHF effectively eliminates neutral current caused by harmonic distortion, improving system stability and safety.
Modular Design
