Power quality analyzer SMG7000

signalmonitoringfor electrical networks

The SMG7000 is a handheld power quality analyzer for on-site inspection and long-term monitoring of electrical networks. It detects waveform distortion, harmonics, voltage fluctuations/flicker and three-phase imbalance while providing accurate electrical parameter measurement and vector analysis for industrial applications.

Key features

• Portable, high‑precision instrument for detecting waveform distortion, harmonics, voltage deviation, flicker and phase imbalance.
• Measures voltage, current, active/reactive/apparent power, phase angle, power factor and frequency with high accuracy.
• Vector diagram display for rapid verification of wiring and phase relationships.
• Current measurement via clamp transformers (non‑intrusive); clamp options: standard 5 A/25 A, optional 100 A/500 A and 400 A/2000 A.
• Comprehensive AC power quality analysis from utility to load: frequency deviation, voltage deviation, voltage fluctuation, flicker, three‑phase unbalance and harmonic content up to 63 orders.
• Single‑phase and simultaneous three‑phase waveform display for voltage and current.
• Screen‑lock function on test interfaces to facilitate reading and analysis of captured data.
• Load fluctuation monitoring and trend recording of parameters (voltage, current, active/reactive/apparent power, frequency, phase) at configurable intervals.
• Supports dynamic monitoring and on‑site adjustment of electrical equipment for commissioning and power correction.
• Evaluation of reactive power compensation and filter device dynamics with quantitative reporting.
• Configurable storage interval and high‑capacity internal memory enabling up to 18 months continuous recording at 1‑minute intervals.
• USB interface for easy data transfer to PC and compatibility with back‑office data management software.
• Built‑in calendar/clock for timestamping; large color LCD and conductive silicone keypad for field use.
• High‑capacity rechargeable lithium‑ion battery and compact, lightweight housing for portability.
