Hioki PQ3198 Power Quality Analyzer

Overview

The Hioki PQ3198 is a robust power quality analyzer designed for field personnel analyzing power characteristics in complex systems. It reliably captures the full range of power anomalies including momentary interruptions, voltage drops, and frequency fluctuations while recording trends to help investigate causes of unexpected equipment malfunctions.

With Class A compliance per IEC 61000-4-30 Ed. 2, the PQ3198 performs standard-mandated measurement tasks including gapless continuous calculation, event detection (swells, dips, interruptions), and GPS-based time synchronization. The isolated fourth voltage channel enables simultaneous measurement of power and efficiency across two circuits with different voltages, such as AC input and DC output of EV rapid chargers.

Key Features

• Class A compliance with IEC 61000-4-30 Ed. 2 standard
• Voltage range: 0–600V RMS with ±0.1% accuracy
• Current measurement: 500 mA to 5 kA AC (sensor dependent)
• Isolated fourth voltage channel for dual-circuit power and efficiency measurement
• Broadband voltage measurement from 2 kHz to 80 kHz for high-order harmonics
• Peak transient voltage measurement up to 6000V (requires optional sensors)
• Supports 40–70 Hz fundamental frequency with up to 20 kHz carrier frequency for inverter measurement
• Simultaneous recording of event waveforms and trend graphs
• Automatic sensor detection to prevent erroneous measurements
• GPS optional for time synchronization
• Included PQ ONE software for detailed data analysis and report generation

Applications
