Key features
Waveforms & phasors
Real‑time display of 4‑channel voltage & current plus automatic phasor diagrams.
Harmonics to 50th
Per‑phase harmonic ratios and THD for voltage & current with bar‑chart view.
Peak, Min/Max
Peak values and half‑cycle RMS min/max for voltage & current.
Power & energy
Active, reactive, apparent by phase & total; energy (Wh, varh, VAh).
Flicker (PST)
Short‑term voltage flicker analysis for 50/60 Hz networks.
Transients & alarms
Detect and record up to 150 transient events; 12,800 alarm logs with thresholds.
Where the PQA-8000 excels
Troubleshooting
Identify dips, swells, interruptions, transients and inrush current events.
Compliance & audits
Document power quality per phase with long‑term trend recording.
Optimization
Analyze PF, DPF, THD and unbalance to reduce losses and downtime.
Commissioning
Baseline measurements for new installations in industrial and commercial sites.
