HIOKI Power Quality Analyzers

PQ3198-power-quality-measurement

Reliable Power Quality Measurement for Monitoring and Compliance

HIOKI’s Power Quality Analyzers provide precise measurements for monitoring, troubleshooting, and compliance testing. The PQ3198-94 records voltage dips, harmonics, and transients to IEC 61000-4-30 Ed.3 Class A – ideal for energy audits and long-term power quality analysis.

The PQ3100 enables fast on-site setup for maintenance and field troubleshooting. Both models reliably capture voltage, current, power, and frequency on all conductors using a wide range of HIOKI current sensors and enable easy, structured reporting with the free software PQ One.

1According to IEC 61000-4-30 Ed.3, Class A offers higher accuracy and reliability in power quality measurements compared to Class S. It requires strict measurement procedures, precise time synchronisation and a wider range of parameters, making it suitable for international comparisons and detailed analyses. In contrast, Class S is designed for basic monitoring with limited accuracy and fewer functions.
