HIOKI PQ3198 Power Quality Analyzer – Class A, Wide-Band & Supraharmonics

Overview
The HIOKI PQ3198 is a high-precision, portable power quality analyzer designed to monitor, record, and analyze anomalies in electrical systems. It satisfies IEC 61000-4-30 (Edition 2 / Class A) standards for power quality measurement, making it suitable for critical industrial, energy, EV charging, and infrastructure applications. The unit is engineered with an expansive measurement bandwidth, enabling detection of supraharmonics, transient overvoltages, flicker, voltage sags/swells, interruptions, and waveform distortions. With isolated channels and versatile input configurations, it supports dual-circuit measurement for AC and DC systems simultaneously.

Key Features

• Class A accuracy per IEC 61000-4-30 for voltage, current, power, frequency measurements.

• Wide-band measurements: high-order harmonics (supraharmonics) up to ~80 kHz, transient voltage peaks up to 6000 V, frequency spectrum up to ~700 kHz for certain events.

• Dual-circuit measurement capability: CH1-3 and CH4 are isolated; supports simultaneous AC and DC circuit measurement or input/output benchmarking (e.g., of inverters, EV chargers).

• Supports multiple wiring configurations: 1-phase 2-wire, 1-phase 3-wire, 3-phase 3-wire, 3-phase 4-wire.

• Good dynamic range for current measurement (flexible sensors) up to 6000 A AC.

• Supports 400 Hz line systems and inverter carrier frequencies (fundamental 40-70 Hz with carriers up to ~20 kHz).

• Transient detection and event capture: voltage sags, swells, interruptions, flicker, waveform abnormalities.

• Interface and storage: SD/SDHC card, USB, LAN (HTTP/FTP), color TFT display for onsite review.

• Battery powered + AC adapter: portable for field use.

Applications
This instrument is well suited for:

• Monitoring power quality at industrial plants, data centers, factories.

• Evaluating and verifying input/output of EV fast-chargers, solar inverters, UPS systems.

• Renewable energy systems (photovoltaic, wind) where AC/DC and supraharmonics matter.

• Power utilities and substation monitoring.

• Preventive maintenance & fault diagnosis: identifying causes of voltage sags, flicker, equipment failures.

• Building management, large infrastructure where reliability and compliance are essential.

【FAQ】（3-5 问答，用于 Rank Math 的 FAQ schema）

1. Q: What standard does the HIOKI PQ3198 comply with for power quality measurement?
   A: The PQ3198 complies with IEC 61000-4-30 (Edition 2 / Class A), ensuring high accuracy and standardized measurement of voltage, current, frequency, flicker, sags, swells, interruptions, and other quality parameters.

2. Q: Can the PQ3198 measure both AC and DC circuits simultaneously?
   A: Yes. It has an isolated CH4 channel which allows simultaneous measurement of a separate circuit. For example, you can measure input (AC) and output (DC) of an inverter or EV charger at the same time, provided you use the correct AC/DC auto-zero current sensor.

3. Q: What is the maximum frequency range and harmonic order supported?
   A: The PQ3198 supports measurement of high-order harmonics (supraharmonics) up to approximately 80 kHz and transient voltages up to ~700 kHz for certain event capture. Fundamental frequency supported ranges for inverter work are typically 40-70 Hz with carrier frequencies up to ~20 kHz.

4. Q: What is the maximum current and voltage the PQ3198 can handle?
   A: For voltage it can measure up to 600 V rms on channels, with peak transient voltages up to 6000 V. Current measurement depends on the attached sensor; with appropriate sensors it can measure up to 6000 A AC. Accuracy depends on the sensor used.

5. Q: What interfaces and tools are available for data analysis?
   A: The device supports SD/SDHC cards for onboard storage, USB2.0 and LAN (HTTP/FTP) for data transfer and remote connectivity. Analysis and report generation can be done using the PQ ONE software provided by Hioki.
