Power Quality Analyser

Power quality, harmonics, flicker and waveforms monitor.

The Power Master 7000 is a user-friendly, comprehensive, compact and cost-effective power quality monitoring and trouble-shooting unit.

Highly commended in the Electrical Industry Awards 2009, the Power Master 7000 is a user-friendly, comprehensive, compact and cost-effective power quality monitoring and trouble-shooting unit.

It offers virtually everything needed to monitor and record power for surveys and audits. It includes 4 voltage input channels capable for measuring 0 to 600 Vac and 4 current input channels for use with voltage output current clamps, or Rogowski Coil sensors supplied. Twelve pre-stored connection configurations are set for 3 phase, 2 phase and single phase measurements. Users can also configure their own set-up and math calculation requirements and save them to non-volatile memory.

The PM7000 complements the Adaptive Store function with intelligent Waveform Capture. This real-time, auto-ranking mechanism is able to track and rank multiple categories of transient and other problem event types. It discards smaller events when larger ones occur, which means the best, most revealing events are captured without any prior knowledge of what might happen – and without wasting store, and without any re-arming time. This makes the whole waveform capture process sensitive/generous/sensible, abstemious and efficient instead of profligate – so data transfer, storage and search times are minimised. Like the benefits of Adaptive Store, these are also achieved without setting any thresholds! The PM7000 supports EREC G5/5 recommendations.

Key Features

• Cat IV 600V Phase A powered Power Quality Analyser.
• Flicker measurements to IEC61000-4-15: Instantaneous Flicker Sensation, Short Term and Long Term Flicker Perceptibility.
• Single Cycle Adaptive Storage™ recording process provides extremely high resolution over long recording periods.
• 32 Troubleshooting channels with single cycle detail.
• General Parameters: Over 470 channels which record automatically for reporting to the Standards.
• Auto-Ranking Waveform Capture: High speed waveform capture ranked for disturbance severity, 7 types of disturbance captured: Transients, falls (sags), rises (surges), rings, notches, THD, Total Harmonic Value. No thresholds need to be set.
• Harmonics to the 50th (standard): THD and individual harmonics to the 50th as standard. As well as using the 32 detailed recording channels, record 1-50th harmonics on all voltage and current channels in General Parameters every measuring session (400 parameters).
• Interharmonics and individual harmonics to the 127th (optional): As well as using the 32 detailed recording channels to record individual harmonics up to the 127th, record the 1-100th harmonics all at the same time on either 4 voltage or 4 current channels in General Parameters.
• Supports ENA Recommendations G5/4 and G5/5
• Bi-colour, status LEDs, externally visible, show recording/memory/voltage/power conditions.
• Bluetooth, Ethernet, USB, USB Flash Drive connectivity.
• Comes with Pronto for Windows software, a highly regarded data recovery and analysis package.
• Hook-Up Checklist with photos and reference vector diagrams to give confidence of correct hook-up whether 1st or 101st time of using the unit. 3 versions are available to distinguish between European Union, USA and Asian (Australasian) phase colours. (NB these checklists will open in a new window.)
• Configuration Guide lists in detail the 12 pre-stored configurations in the logger and shows how to set-up the PM7000 to get live recordings in just 15 minutes.
