Hioki PQ3198 Power Quality Analyzer

Hioki PQ3198 Power Quality Analyzer

The Hioki PQ3198 is a high-end power quality analyzer for investigating power supply anomalies and their causes, complying with the IEC 61000-4-30 Class A standard for reliable, standards-comparable measurement. It captures the full range of power quality problems — transient voltages, swells, dips, interruptions, frequency fluctuations and harmonics — in a single instrument.

Key Features

• IEC 61000-4-30 Ed.2/Ed.3 Class A compliant — gapless continuous calculation and standard-mandated event detection
• Transient voltage capture up to 6000V, as brief as 0.5μs (2MS/s sampling)
• Harmonic measurement including high-order supraharmonics, 2kHz to 80kHz
• Basic measurement accuracy: Voltage ±0.1% of nominal, Current ±0.1% rdg, Power ±0.2% rdg
• 4 voltage channels + 4 current channels; supports 1-phase/2-wire through 3-phase/4-wire configurations
• Isolated 4th voltage channel — measure two separate circuits simultaneously (e.g. verifying EV charger efficiency)
• Simultaneous 1/2-cycle RMS recording during voltage swell, dip or inrush events (30 seconds)
• Records up to 9,999 power quality events and up to 1 year of trend data
• SD memory card recording (2GB/8GB), Bluetooth pairing with compatible LR8410-link data loggers
• Optional GPS time synchronisation
• Includes PQ ONE analytical software

Important: Current Sensor Required

The PQ3198 does not include a current sensor — this must be selected separately based on your current range and access requirements. We stock the CT9667 AC flexible clamp-on current sensor and L1000-05 voltage cord set as standard accessories.

Applications

Investigating equipment failure and malfunction causes; verifying solar power system output quality (flicker, transient voltages, harmonic fluctuations); assessing EV rapid charger power quality and efficiency across two circuits; harmonic and supraharmonic troubleshooting on inverter-heavy installations; formal IEC 61000-4-30 Class A compliance measurement.
