Harmonic Current and Voltage Flicker Analysis System

The Harmonic Current and Voltage Flicker Analysis System comprises three professionally integrated test instruments: the LSHF61000-3-2/3 Harmonic and Flicker Analyzer, LSAIF-503 Flicker Impedance Network, and LSP-1KVA-HF Low-Distortion AC Power Source. This configuration constitutes a comprehensive, high-precision, certification-grade single-phase 31 that fully complies with IEC 61000-3-2 (GB 17625.1) “Limits for harmonic current emissions” and IEC 61000-3-3 (GB 17625.2) “Limitation of voltage fluctuations and flicker”.

The system utilizes a high-speed 16-bit analog-to-digital converter to deliver high-precision, real-time measurement and analysis of critical power quality parameters across the complete range of AC input characteristics. It supports comprehensive harmonic assessment and automated limit evaluation for Class A/B/C/D equipment under test (EUT). The system finds broad application across diverse electrical and electronic products, including household appliances, LED drivers, power adapters, lighting equipment, control modules, EV chargers, and other consumer electronic devices.
