Elcomponent PQPro Power Quality Analyser

The Elcomponent PQPro Power Quality is a specialist instrument for power quality measurement and power system diagnostics, positioned by Elcomponent as its third-generation design in this category. It is built for users who need more than standard energy logging, with capabilities aimed at identifying waveform distortion, voltage disturbances and other electrical anomalies in commercial and industrial systems.

A major strength of the PQPro is its advanced analysis capability. Elcomponent states that it measures AC and DC voltage, current, power and frequency, while also providing waveforms, harmonics, vector diagrams, three-phase voltage and current inbalance, voltage sags and swells, high-speed voltage transients, current inrush and flicker to IEC 61000-4-15. It also supports power quality analysis to IEC 61000-4-30 Class A, making it a strong choice for users investigating detailed supply quality issues rather than basic load surveys alone.

The PQPro is also designed for practical field use and longer-term diagnostics. The measurement engine samples at 1024 samples per cycle (51 kHz), allowing capture of voltage transients down to 20 microseconds or 50 Hz systems, while storage is handled via a plug-in SD card with support for cards up to 32GB. A fully integrated Bluetooth module enables wireless connection to the associated PV II / PowerView PC software, allowing real-time interrogation and easier data review when direct cable access is inconvenient.
