The Hioki PQ3198 is a high-precision Class A power quality analyzer designed for monitoring, recording, and diagnosing electrical anomalies in industrial and utility systems. It captures critical events such as voltage dips, harmonics, transients, and flicker, enabling engineers to identify root causes of power issues and ensure compliance with IEC 61000-4-30 standards. With simultaneous logging and waveform capture, it is ideal for detailed power quality audits and troubleshooting. Technical Highlights: Voltage measurement: up to 600 V RMS | Transient capture: up to 6 kV peak | Current range: up to 5 kA (sensor dependent) | Harmonic analysis: up to 80 kHz | Accuracy: Voltage ±0.1%, Power ±0.2% | Event recording: up to 9999 events, long-term logging up to 1 year | Measures dips, swells, flicker, unbalance, inrush, and power parameters | Interfaces: SD card, LAN, USB for data transfer Ideal for power quality studies, energy audits, troubleshooting, and compliance analysis in complex electrical networks.
