About The PM7500

The PM7500 Power Quality and Energy Monitor, an upgraded replacement of the PM7503, is a panel mounted variant of our top of the range PM7000 Power Quality Analyser. As with the PM7000 and PM7000FLM, as well as recording numerous power quality parameters, the PM7500, with our Enhanced Harmonics upgrade, is able to simultaneously record individual Harmonics to the 100th on 3 Voltage and 3 Current channels, and to the 50th on the remining 2 channels, as well as the Interharmonic and Interharmonic Sub groups to the 100th as required by ENA Recommendation G5/5.

The PM7500 also has Dual Frequency measurement capability, measuring frequency to 0.001Hz resolution on V4 as an independent fast frequency option with an accuracy of 0.002Hz and noise typically less than 0.001 Hz RMS. This fast frequency measurement is being used to fulfil the National Grid Dynamic Containment requirement of providing ongoing, time-synchronised, gapless data packets, over TCP-IP, of the power and high resolution frequency measurements. These values are required hourly by National Grid to ensure the Dynamic Containment provider is capable of responding as per their Dynamic Containment agreement. Read more about our Dynamic Containment offering here.

The PM7500 records events, trends and transients with min/max logging. As standard, it can also record >500 channels simultaneously and has automatic sag/swell monitoring down to single cycle on 32 channels using our unique recording regime Single Cycle Adaptive Store. As well as measuring flicker and other parameters, the standard unit measures and records harmonics up to the 50th order. As explained above, with our Enhanced Harmonics upgrade, the user can record individual current and voltage harmonics, interharmonics and Interharmonic Subgroups to the 100th simultaneously.

The PM7500 has waveform capture at 384 samples/cycle at 50Hz (19.2kHz) and Ethernet, USB and Bluetooth communication. It is also compatible with Nortech iHost and can be rack-mounted if required.

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 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.
  • Dual /Fast Frequency Option: Independent frequency variation measurement on V4. Resolution to 0.001Hz (frequency), single cycle (time), latency ~3 cycles. FFR (V4) measurement range 40-70Hz.
  • Dynamic Containment seamless hourly data download facility: Ongoing download facility of time-synchronised, gapless data packets, over TCP-IP, of the power and high resolution frequency measurements required by National Grid to prove a Dynamic Containment Provider’s readiness to act with their fast-acting frequency response.
  • Fault Level prediction Option: Peak and RMS fault current predictions generated by observing natural disturbances on the network. See PM7000 FLM product page for more details.
  • Bi-colour, status LEDs, externally visible, show recording/memory/voltage/power conditions.
  • Bluetooth, Ethernet, USB, USB Flash Drive connectivity.
  • Volt free contact closure for status output.
  • Comes with Pronto for Windows software, a highly regarded data recovery and analysis package.
  • Rack-mounting kit available on request (2U x 19 inches)

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.

That’s a hell of a piece of Kit!

That’s a hell of a piece of Kit!

Now I’ve seen what it can do I’m going to mention it to another customer here in the UK who I know is having trouble.”

Bluetooth functionality with PMScreen and real time monitoring is sensational.

Thank you so much for attending to [my support query], and so quickly! Very impressed with these [PM3000] power analysers and the Bluetooth functionality with PMScreen and real time monitoring is sensational.

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.

It’s an amazing piece of Kit!

I certainly will be hiring another PM7000 again. It’s an amazing piece of kit!

Stuart Turner, PCAS (Power Control and Automation Solutions) Ltd, Feb 2020
I have been quite astounded at the detail the Outram Data Logger has captured.

During communications regarding the 3 PM7000TIs that Bob is managing remotely, with new data sent back to him over email every 24 hrs, he told us that he has been finding detail in the recordings he never thought he would see. “I have been quite astounded at the detail the Outram Data Logger has captured.”

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.

…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.

I have used data loggers in the past… Not in the same league as the Outram equipment

Thank you for all your fantastic efforts yesterday.

I have used data loggers in the past but they were not in the same league as the Outram equipment.

Last December when Network Rail asked me to install PQ monitoring I looked at hiring a couple of [competitor] PQ monitors. I had a Network Rail Graduate alongside me and I thought it would be a good learning exercise for him. As I began to understand the railway electrification system I realised [these] were a non-starter, so when the local electricity board ‘turned the screw’ I decided to look deeper.

I discovered Outram and when I read about your collaboration with Scottish Power I immediately realised the Outram equipment was the only one to consider. From what I have seen since yesterday morning I know I was correct in contacting your company.

…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.
