Measurement and recording per IEC 61000-4-30 on a 7-inch touchscreen
APQM-707
Power quality analysers
APQM-707
Class S power quality analyser
A portable power quality analysis centre, self-contained and touchscreen-operated.
Class S in the hand
The APQM-707 measures, analyses and records the parameters of DC and 50/60 Hz networks per class S of IEC 61000-4-30: voltages on five inputs up to 760 V (±0.5% Unom), currents on four inputs up to 6 kA depending on the clamp, frequency, P, Q, D and S powers, energies, cosφ, tanφ and power factor.
Watching the network live
The largest touchscreen in its class — 7 inches, 800 × 480 pixels — displays oscillograms, time plots, the phasor diagram, harmonics up to the 50th order, THD, PST/PLT flicker, unbalance and inrush current. Dips, swells and interruptions are recorded with their oscillograms and half-cycle RMS graphs, and the supplied stylus allows work with dielectric gloves.
Main features
- More than 10 years of recording on a removable memory card.
- Li-Ion battery: measurement continues through interruptions.
- Powered from the measured network or the mains adapter.
- Networks from 58/100 V to 400/690 V, direct or via transducers.
- Built-in energy cost calculator.
- Four 3 kA flexible clamps in the standard set.
Applications and safety
Applications
- Industrial maintenance and on-site diagnosis of disturbances.
- Energy audits and control of energy costs.
- Analysis of photovoltaic installations and their inverters.
- Professional power quality analysis services.
Ready for the harsh environment
The CAT IV 600 V measurement category and the IP51 housing with hinged lid protect the analyser on site. It works in single-phase, split-phase, star with or without neutral, delta and Aron networks, with voltage and current transducers, and its PC analysis software produces EN 50160, IEEE 519 and NEC 220.87 reports.
The PC analysis software, supplied as standard, turns the records into reports.
Software & applications
The analyser and its software
The analysis software configures the APQM-707, reads the data from the memory card over USB and displays the network parameters in real time: oscilloscope, time plots, phasor diagram, multiple measurements, harmonics with their powers and interharmonics.
From recording to report
The data are presented in tables and interactive graphs, and reports are generated per EN 50160, IEEE 519, NEC 220.87 and other references — including photovoltaic micro-installations up to 50 kW, with the breakdown of active power states.
What the software provides
- Configuration of the analyser and card reading.
- Live view of waveforms and harmonics.
- EN 50160, IEEE 519 and NEC 220.87 reports.
- Support for several analysers and updates.
