The Hioki PQ3198 is Hioki’s flagship model for advanced power quality analysis and complies with IEC61000-4-30 Ed. 3 Class A, ensuring the highest level of measurement accuracy and repeatability. The instrument is engineered to capture extremely short and complex disturbances, including transients up to 6000 V with a 2 MS/s sampling rate, as well as supraharmonics in the 2 kHz to 80 kHz range. This makes the PQ3198 particularly suited for troubleshooting modern electrical systems featuring inverters, variable-speed drives, photovoltaic installations and fast EV chargers.
The instrument provides a separately isolated fourth voltage input, enabling simultaneous measurement of two circuits—such as AC input and DC output in charging stations or inverter systems. This capability is essential for verifying efficiency, energy balance and operational stability in power conversion systems.
The PQ3198 logs trend data for all measurement parameters and automatically records waveforms during events such as dips, transients, harmonic disturbances and frequency anomalies. In combination with the advanced PQ ONE software, users can perform full power quality assessments according to EN50160 and IEEE519, generate reports and quickly identify the root causes of disturbances.
