Overview

The Portable Power Quality Analyzer - PQS-1001 is engineered for professionals who need reliable, repeatable, and connected power quality measurements in the field. Designed to simplify complex audits, it combines a high-accuracy Class S measurement platform with wireless tablet operation and cloud-based reporting to deliver complete visibility into electrical system performance.

Accurate, Connected, and Ready for the Field

Built for real-world environments, the PQS-1001 pairs a rugged main unit with a Wi-Fi-enabled tablet interface that provides remote control and data visualisation. Engineers can safely perform measurements without direct panel contact, while all captured data is automatically synchronized to a secure cloud dashboard for analysis, reporting, and record-keeping.

Comprehensive Power Quality Analysis

Conforming to IEC 61000-4-30 Class S, the PQS-1001 captures all key parameters essential for diagnosing system health and performance. It measures:

Voltage and current up to 1000 V / 3000 A
Harmonics up to the 51st order
Flicker, dips, swells, and transients
Power factor, active/reactive power, and energy values
Inrush current and waveform oscillography

These measurements help identify voltage disturbances, waveform distortions, and harmonic imbalances that affect power reliability and equipment efficiency.

Flexible Current Measurement

The PQS-1001 supports both Clamp and Rogowski current transformers, allowing current measurement from 10 A to 3000 A across diverse applications. The universal CT interface enables easy adaptation to plant, utility, and renewable energy systems without additional setup.

Safe and Efficient Operation

Every measurement is controlled through the wireless tablet application, keeping the operator safely away from live panels. The interface offers guided workflows, photo-tagging, and route-based asset management to ensure consistent and traceable measurements across multiple locations.

From Measurement to Insight

With cloud connectivity, automated Excel/PDF reports, and historical trend analysis, the PQS-1001 enables users to transition seamlessly from field measurement to actionable insights. It’s a complete, connected solution for professionals who demand accuracy, safety, and reliability in every power quality study.
