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! The PM7000 can also measure all the harmonic requirements of the EREC G5/5 recommendation.

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.

Three Different Recording Regimes

Single Cycle Adaptive StoreTM
Greatest Disturbances Waveform Capture
General Parameters

This is the information storage technique used on our 32 detailed recording channels. During the recording the PM7000 automatically alters the detail of the recording whenever a disturbance occurs i.e. whenever there is an anomaly in the recording. This means that when nothing ‘interesting’ is happening the PM7000 does not record every cycle but gives the average, max and min during that period. When something ‘interesting’ happens the analyser records in much greater detail, down to a single cycle, without the user having set thresholds. This makes analysis of the recording much easier and faster, being able to zoom into the causes of power quality problems much more quickly and easily.

Using Adaptive Store is considerably faster and simpler than setting and adjusting trigger levels as required by other power quality monitors: a process that can lead to an operator taking weeks to ‘zero in’ on the problem, as well as needing to wade through much unnecessary data.

Please read our press release for the specific application.

This Auto-Ranking Waveform Capture system automatically keeps the sub-cycle waveforms of the most serious events captured during a recording, discarding the least important, without the need to set any thresholds. The user can choose how many waveforms he wants of 7 different types of event on each detailed channel measured and just get the worst ones most likely to be the cause of his power quality issues. This saves a lot of time and effort analysing the data.

Application for Auto-Ranking Waveform capture – See below how a captured disturbance led to solving a problem?

Could this short lived transient have caused the voltage collapse which came 8 seconds later?

We can zoom in and see that the waveforms corresponding to the voltage transient have been captured, giving us a useful picture of what happened to the different Phases. With the PM7000 you can zoom straight to the problem without having to trawl though mountains of data.
Waveform recordings are continuously re-triggerable and do not require re-arming, so no data is missed.

Over 470 parameters are recorded at a specified interval during every measurement, automatically without any user input. This increases to 1000s with our Advanced Harmonics option, measuring all individual harmonics to the 100th on 6 inputs (and to the 50th on the other 2) as well as sub group and interharmonics (more detail below). If a user forgets to specify a particular parameter on one of the detailed channels mentioned above (Adaptive Store), there’s no need to worry as it will very likely be measured automatically in General Parameters. This reduces the need for repeat recordings, saves time and gives a large amount of trend data on a user or their customer’s site without any further thought from the user.

Software

Our Windows Based Software, Pronto
Data Combinations & Comparisons
Math Data Stream Generation

We believe that Pronto is the most comprehensive Power Quality Monitoring Software in the industry. It is well suited to basic compliance testing of data as well as more detailed analysis work. The power and flexibility of the software soon become apparent when the user zooms in quickly to data of interest to then view and present any combinations of data in a clear and concise fashion. The user can easily export tables, copy and paste graphs, add in and remove data parameters quickly and efficiently, as well as effortlessly create templates for both tables and graphs.

Pronto has been developed by Outram Research over the last 30 yrs, originally designed for the process industry. Not only can it manage the data recorded by our PM7000 models but it organises effectively the data downloaded from the whole range of Outram Power Quality and Fault Level Monitors including our single phase PM1000Mk2 to our PM7000T (sampling at 1.228 million samples per second).

It is VERY Flexible. The user can do a lot with the data, including the automatic joining together of distinct recordings, and show data from different Power Master Analyser models on the same graph when measuring around the same time.

What makes Pronto unique is the fact that no, or very few, associations have been made regarding any streams of data recorded. Power Quality data logged by the Power Master Series (including thousands of parameters) can be presented in a very large number of different combinations, making manipulation of the data easy for the user. Data from different Power Master or Ranger models can be viewd together for easy comparison. We understand that our software is also significantly faster to draw than other products, making a large difference to the time spent analysing data.

Nine different parameters presented on the same graph to enable easy comparison of each parameter with any other.

Zoomed in on the graph above, we can see the detail captured on each parameter recorded.

Zooming in more shows the detail captured on each parameter recorded down to single cycle.

The majority of these current spikes and associated voltage dips last less than a second but it is possible to see exactly what is happening. In fact there are around 4 different fridges in use in this recording and each one can be identified by its profile captured by the PM1000 with the same measurement technique also used in the PM7000HF but over 3 phases.

The user can also create Maths data streams using any recorded parameters. They can create averages over 30 sec, 1 min, 5 min, 10 minutes (or in fact any integer time span you choose) which can then be viewed on a graph. (They can also be tabulated). It is possible to choose from any of the maths functions seen here:

Showing the averaging function used in Pronto (1min averages vs Adaptive Store), is another reminder of how important it is to record that single cycle detail in order to carry out the most useful data analysis possible.

Data Visualisation

Tables
Graphs
Automated Reports & Tutorials

Create tables in Pronto of all the data captured (exportable into Excel and PQDif) and choose how the data is presented. Whether you choose an average over a period to report against the Standards or other options, you can also include the max and min (with times), the mean, 95th percentile, 5th percentile (percentiles are selectable) in a summary section in your table… there are a huge number of possibilities.

Below is a table of data measured using Adaptive Store, averaged over 10 min intervals (rows 16-1011 are hidden in this case), with the mean, max, min and 95th and 5th percentiles.

If you would like to be able to recreate your graph or table, save it as a template to create it again with minimal clicks from the data in your next recording, including formating and title.

Our PM7000 range can also measure 1000s of General (Interval) Paremters as well as carry out Auto Ranking Waveform Capture.

Pronto can present harmonic analysis of captured waveforms, in some cases displaying the apparent direction of those harmonic sources.

Create an extensive Harmonics Survey Report with a few clicks using our G5/4 Reporting function. We use this as the basis for reporting to the updated G5/5 harmonics requirements so it’s a great tool for whatever reporting requirements you have.

We also have tutorials to help users quickly get up to speed with enhanced features of the software. You can find more at

Advanced Harmonics & Dynamic Containment

Advanced Harmonics
Dynamic Containment
Instantaneous Flicker Sensation

With our Advanced Harmonics upgrade PM7000 users can measure individual harmonics up to the 127th order as well as Interharmonics and Sub Group Harmonics. Interharmonics are important when measuring the disturbances generated by appliances not related to the mains eg. Mechanical or electrical resonance.

The PM7000 has automatic and simultaneous measurement of harmonics(1) to the 100th on 6 inputs (V & I), and to the 50th on remaining 2 inputs as well as individual inter-harmonics between fundamental and second harmonics and inter-harmonic sub-groups to the 100th (3 x V only).
Individual harmonics, inter-harmonics, groups and sub-groups to the 127th harmonic on any phase can also be measured on detailed Adaptive Store channels. THD and THC also available to the 100th Harmonic.

(1) As required by the EN61000-4-7 Class I and G5/5 Standards, harmonics recorded as General Parameters are Harmonic sub-groups comprising the Root Sum Square of the harmonic itself plus the two adjacent 5 Hz lines.

Our Dual Frequency option adds an additional, independent, precision frequency measurement to a PM7000/ PM7500 with resolution to 0.001Hz used in conjunction with our Dynamic Containment seamless hourly data download facility to allow the user to fulfil their requirements for National Grid (UK)’s Dynamic Containment Monitoring

Although analysers adhering to the standard IEEE1453 (based on IEC61000-4-15) provide adequate Flicker measurements, the Outram PM7000 was the first analyser to also include the required Instantaneous Flicker Sensation output. Instantaneous flicker sensation is the intermediate result needed to produce the averages required by the Standard, and since we are the only design house with the recording mechanism Adaptive Store, mentioned earlier, it can be brought forward to be viewed as live results, by the user.
