About the PM7000

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!

Applications include:

Trouble shooting unknown power quality issues – Our unique recording regime Adaptive Store is especially useful for identifying and locating problems on your network, recording down to a single cycle the instant events occur without setting any thresholds. Unique precise capturing of sudden changes eg. transients, current spikes, harmonics, drop-outs and brown-outs to extremely high resolution makes detecting problems on your power distribution system easier. The PM7000 is often used when other units without this capability have failed to find a problem.

Real time troubleshooting – Live results, harmonics, waveforms and EN50160 comparisons can all be viewed on an Android tablet or mobile phone via Bluetooth comms even whilst background recording is taking place. Get a head start on your site analysis right from the word go.

New Equipment Installation – Benchmark before and check after the installation of new equipment to ensure quality of service has been maintained.

Power Quality Surveys – record all parameters and create necessary graphs and tables to create your own professional reports. >470 channels are measured in General Parameters to ensure nothing is missed during each recording. G5/4 reporting available from April 2016.

Long term monitoring – Discover solutions to hard to find or intermittent problems. Record indefinitely in FIFO mode until the event occurs again. If required download each recording automatically to a hard-drive or memory stick or transfer data via Wifi/3G/4G using our PMGateway App or Ethernet. Discounts available for long term hire.

Speed up critical equipment recovery – Monitor important equipment to capture power quality events if and when it malfunctions. Use this information to get it back online more quickly.

Harmonics Analysis – Monitor 2-100th Harmonic on 4 voltage or 4 current channels or 2-50th on 8 channels (400 harmonics) at the same time. Make an assessment of your site conditions whilst checking compliance with the standards. G5/4 reporting available from April 2016.

Customer complaints – Solve customer complaints including voltage or flicker problems using the ability to compare any data streams on the same graph in the Outram/Ranger Software, Pronto. E.g. RMS voltage and instantaneous flicker sensation (and any others) on the same graph. Finding the problem quickly using Adaptive Store recording regime means minimum customer disruption.

Measure in remote locations – Automatic restart when power returns if unit is being powered off voltage measured.

Load Distortion and Imbalance

Preventive Maintenance – keep a track on your power quality to detect any problems before they cause your equipment damage or end up in costly down time.

Fast Transient Capture – waveform capture to 1.228MHz with automatic ranking in Pronto to help you zoom in to the most important waveforms in the recording in seconds. Sags, Surges, Transients, Rings, Notches, THD, TH Current are all triggers.

Network Characterization – measure non-sinusoidal and unbalanced systems.

Power Quality Software: Our comprehensive and very flexible Pronto software is the same for all Outram/Ranger Equipment so even when hiring a variety of models you will still use the same software each time.

Recent hire applications include:

  • Troubleshooting solar farm commissioning issues
  • Solving connection problems at a grid tied Combined Heat and Power Plant (CHP)
  • Instability issues on wind farms
  • Effects on power quality of malfunctioning large materials handling systems/Cranes
  • Monitoring switchover from live to backup power and back again
  • Measuring either side of a UPS – Differential inputs allow simultaneous measurements to asses UPS quality
  • Determining whether power quality issues are being imported or exported
  • Measurement of capacitor switching.

…PM3000 is the best product in my shop

The reason I think your PM3000 is the best product in my shop is the reliability and the software. I use 5 different brands of recorders and this one by far has been the most reliable. The software updates are great, with the 60 day reminders. The layout of the software and every single function make it simple and user friendly unlike most products.
