Hioki PW3198 Power Quality Analyzer
The Hioki PW3198 (and its current generation PQ3198) is a flagship high-precision power quality analyzer engineered to comply with strict IEC 61000-4-30 Class A standards. Designed for mission-critical electrical infrastructures, it records high-speed transient overvoltages up to 6000 Vpeak at 2 MHz sampling, analyzes high-order supraharmonics up to 80 kHz, and enables concurrent AC/DC dual-circuit efficiency measurements.
Key Features & Benefits
-
-
Full IEC 61000-4-30 Class A Compliance: Ensures standards-grade precision, zero gapless data loss, and benchmark testing for utility grid handovers.
-
6000 V Transient Overvoltage Capture (2 MHz Sampling): Detects fast-rising voltage spikes down to 0.5 µs duration caused by lightning, capacitor switching, and contact arcing.
-
Dual-Circuit AC & DC Measurement: Isolated 4th channel allows simultaneous efficiency and power testing of inverter AC inputs and DC battery/charger outputs.
-
High-Order Supraharmonics Analysis (2 kHz to 80 kHz): Uncovers high-frequency switching distortion generated by variable-frequency drives, EV fast chargers, and solar power converters.
-
400 Hz Aviation & Marine Line Support: Expands measurement capability from standard 50/60 Hz power grids to 400 Hz electrical lines in aerospace and naval installations.
-
Integrated PQ ONE Compliance Software: Generates standardized compliance summary reports (EN 50160, IEEE 519) with one-click automated statistics.

Description
Engineered for electric utility grid engineers, datacenter facility directors, and EV charging station developers, the Hioki PW3198 / PQ3198 delivers laboratory measurement performance into field environments. Unlike entry-level loggers, its Class A certification guarantees gapless, continuous mathematical calculations across all standard parameters—including voltage dips, swells, interruptions, harmonic phase angles, and IEC flicker—providing legally defensible data for contractual dispute resolution and grid interconnection agreements.
