A power quality analyzer is a multi-channel instrument that continuously monitors and records voltage, current and power across multiple phases, capturing anomalies like transient voltage spikes, swells, dips, interruptions, frequency fluctuations and harmonic distortion. Unlike a simple power meter that shows a live power reading, a power quality analyzer is built to investigate what went wrong and when β recording detailed event waveforms alongside long-term trend data.
Why this matters: Equipment failures, nuisance trips and process disruptions are often caused by power quality problems that a simple voltage check will never reveal β a brief transient, a harmonic-heavy load elsewhere on the same supply, or a voltage sag lasting a fraction of a second. Investigating these root causes requires continuous, standards-compliant recording.
Key advantage: Identifying the actual cause of a recurring equipment fault can prevent repeated failures that each cost far more than the investigation itself.

The PQ3198 and PQ3100 give field engineers standards-compliant power quality investigation:
The PQ3198 complies with Class A (the highest standard, for legally defensible and cross-instrument-comparable measurement); the PQ3100 complies with Class S, suited to general troubleshooting at a more accessible price point.
Captures transient voltages (up to 6000V on the PQ3198), voltage swells, dips, interruptions, frequency fluctuations, and harmonics including high-order supraharmonics up to 80kHz β the full range of power quality problems in one instrument.
Records trend data continuously alongside detailed event waveforms whenever an anomaly occurs, so you have both the long-term pattern and the precise detail of every event β up to 9,999 recorded events and a year of trend data.
Connects to Hioki's range of clamp-on and flexible current sensors, letting the same analyzer scale from small circuits to heavy industrial feeders depending on the sensor selected.
Records to SD memory card for extended unattended monitoring, with PQ ONE analytical software for reviewing, comparing against standards compliance, and reporting on captured data.
Both share the same core measurement architecture β the PQ3198 is the higher-precision flagship, the PQ3100 the more accessible mid-range option:
| Model | Best For | Harmonics | IEC 61000-4-30 Class | Max Transient Voltage |
|---|---|---|---|---|
| PQ3198 | High-precision investigation, legally defensible compliance measurement | Up to 80kHz (supraharmonics) | Class A (flagship) | 6000V (0.5ΞΌs resolution) |
| PQ3100 | General field troubleshooting at a more accessible price point | Standard harmonic analysis | Class S (mid-range) | 2200Vpeak |
Power quality investigation supports these use cases:
Identify the root cause of nuisance trips, equipment malfunctions and process disruptions that a simple voltage check cannot explain, including issues where one device on a shared supply affects another.
Check power conditioner output voltage fluctuations, flicker, transient voltages, and harmonic voltage/current components at the grid interconnection point of a solar installation.
Verify the power quality delivered by EV rapid chargers; the PQ3198's isolated fourth voltage channel allows simultaneous power and efficiency measurement across two separate circuits.
Identify harmonic and supraharmonic distortion from VFDs, inverters and other non-linear loads, including higher-frequency components increasingly common as inverter-based equipment becomes widespread.
Monitor voltage, frequency and power quality at the point of grid interconnection for compliance verification and ongoing quality assessment.
Perform IEC 61000-4-30 compliant measurement for formal power quality compliance documentation, using Class A (PQ3198) where legally defensible, cross-instrument-comparable results are required.
