About the PM4000

Full Power Quality Survey. No Fuss.

  • Pre-loaded PQ survey configuration means hook it up and start recording. No thresholds, no fuss, all the results you need.

Nuisance Tripping? Record without thresholds.

  • No thresholds need to be set for detailed event or waveform capture. Is it the supply or your installation causing the trip?

Safe, Long Term Recording.

  • A 600V Cat IV (1000V Cat III) analyser powered off phase A or 12Vdc charger. Remote comms available via our mobile app. PMGateway.
  • With FIFO mode and automatic download to USB, carry on recording until a specific event occurs, then collect your data.

Solve Customer Complaints Quickly.

  • Advise customers competently on voltage surges, dips, flicker or harmonics problems comparing any data streams in the Outram Research Ltd Software, Pronto for Windows, e.g. RMS voltage and Instantaneous Flicker, on the same graph.
  • Minimise customer disruption by finding problems quickly using Adaptive StoreTM. Record single cycle detail during events with no thresholds set.
  • Comprehensive, quick, consistent reports using graph and table templates in Pronto for Windows.

Preventative Maintenance

  • Monitor your power quality over time to detect any problems before they cause equipment failure or costly down time.

Check Pre and Post Equipment Installation

  • Benchmark before and check after the installation of new equipment to ensure quality of service has been maintained.

Monitor Your Motor Performance.

  • Are your machines deteriorating due to poor power quality? Observe the supply to your motors, checking for unbalance and harmonics in real time.

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.

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.

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 2-50th Harmonics on any voltage or current channel. Histogram of harmonics available on all captured waveforms.

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 19.2kHz 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.

Customer 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

The Outram PM7000FLM … software made analysis of fault-current straightforward

We found the Outram PM7000FLM useful for capturing data, and its software made analysis of fault-current straightforward. Other methods of data capture can be used, but would require further development to accurately give fault level information; the area where the FLM scores is its ease of use, and also that statistical analysis is applied over the whole test period, rather than at a ‘snapshot’ of one event as our analysis. This makes it less prone to noise and other disturbances on the system.

…calculation of fault level trivial in comparison to the ‘manual’ methods

The Outram equipment (and associated software) makes calculation of fault level trivial in comparison to the ‘manual’ methods.

The analyser did everything that we needed. We were also impressed with how quickly it got across the US.

The analyser did everything that we needed. Rob was surprised at how easily it went on.

We were also impressed with how quickly it got across the US. It was there before we even left [the UK] and we didn’t expect that to happen.

It’s a specialised subject and the support we received from Duncan was second to none.

….Commendable for its ease of use and portability

The Outram equipment is commendable for its ease of use and portability.

…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.

Outram PM7000FLM proved capable of reliably assessing Fault Level

The Outram PM7000FLM and associated software proved to be capable of reliably assessing / calculating fault level from both repeated low-level steps, as well as one-off larger pulses.
