Real Time Fault Level Monitor (RTFLM)
The first ever compact unit capable of measuring Peak and RMS Prospective Short-Circuit Current (Fault Level) in Real Time.
Request a quoteAbout the RTFLM
The Real Time Fault Level Monitor (RTFLM) can deliver MEASURED Prospective Fault Level Results in real time at LV and MV (up to 33kV).
Installed in network substations, the RTFLM is a standalone cubicle designed to collate prospective Fault Level results generated through the measurement of a number of very small artificial disturbances over a short period. Results can be continuously available but are typically averaged over 10 seconds (selectable). The Prospective Fault Level at the measurement point can be transmitted in real time over the SCADA system, making it the first compact instrument capable of generating real time measurements that can be used by those managing the network.
The Fault Level (short circuit current) data can either be requested from the unit when needed or will regularly and automatically be sent back through the network communication system to the relevant control centre, with a view to being used to actively manage the network based on what the Fault Level actually is at the time.
The RTFLM uses the ground breaking technology found in our Natural Disturbances Fault Level Monitor, the PM7000FLM, coupled with a built in artificial disturbance generator to remove the need for a necessary level of ‘activity’ on the network, and a radial network measurement position, to produce results.

Innovation sponsored by OFGEM
The development of the Real Time Fault Level Monitor (RTFLM) has been part of an NIA (Network Innovation Allowance) Project run by SP Energy Networks (SPEN). Stage 1 of this project, currently in progress, is the installation of 2 units on the SPEN Network to accurately predict the MV (11kV) network Prospective Fault Level in Real Time.
Stage 2 of SPENS project, with the inclusion of UK Power Networks (UKPN) into the project team, began in early 2020 was to install a further 8 units on the SPEN network (4 in England and 4 in Scotland) with a further 6 on the UKPN network. This project was to explore how best to actively manage the network based on Real Time Fault Level Results.

What does this mean for the future?
We anticipate installation of these units in substations and at industrial sites worldwide to help combat problems and constraints faced due to Fault Level being either too high (in more densely populated/industrial areas) or too low (in outlying regions).
Sites have already been earmarked in the UK for RTFLM installation to facilitate new customer connections. These are locations with a believed Fault Level Capacity issue, where, following connection, certain circumstances could take the Fault Level over the local rating limit.
Monitoring the Fault Level, obtaining up to date information, will enable the unique situation where a customer can be disconnected when the Fault Level reaches a predetermined limit. The installation of an RTFLM and an agreement to adhere to an Active Network Management Contract of this type is likely to be a far more attractive proposition than a charge for millions of pounds (£) worth of network reinforcement.
This technology will enable:
- Increased network safety, reducing risk of operating above design limits
- Validation of models to release additional firm capacity
- Increased network operability / security. Allow greater interconnection
- The introduction of Active Network Management based on Fault Level
- The offering of a new connection customers the choice of a ‘Flexible Connection’. Agreeing to disconnection when Fault Level reaches a pre-determined limit
- Faster / cheaper connections for customers, increasing the uptake of Low Carbon Technology
- Greater visibility / understanding of the network Fault Level – seasonal variability and contribution from customers

I have had the pleasure of working with the Outram's and their Instruments for over 15 years. Their equipment and hire service has never failed. The technical support is second to none and their friendly approach is always appreciated. I have used many alternatives, but for my needs the Ranger PM equipment is the best by far.
Darren Curtis27/07/2023I needed soem support with my Outram kit, and got it within minutes! Can't fault any of them team, but special thanks to Kate for helping me. May i have many more years of service on my PM3000!
Tower Crescent13/10/2021Fantastic equipment. Brilliant onsite support with their G5/5 and Fault Level Monitor equipment.
Simon Lynd08/02/2021I have used Outram Research previously for Power Quality Surveys and G5/4 G5/5 compliance issues. All reports were well presented, on time and well laid out technically. Staff are approachable and customer friendly.
Robert King07/02/2021Whilst under contract to Network Rail [RIDC] Midlands Test Facility at Asfordby, Leicestershire. I was required to investigate the impact on Power Quality of the 25kV Traction Testing being undertaken. I researched suppliers of Power Quality Equipment and on discovering the involvement Outram Research Ltd has with the Electricity Supply Industry I recommended NR engage them to assist in the data collection focussed on NPS [voltage unbalance]. I found that Outram Research had a very thorough understanding of all the issues associated with Power Quality and could supply and connect the appropriate Outram Data Loggers to enable the capture of the data I required. With the data captured I was able to demonstrate the .25kV traction testing imposed far less voltage unbalance on the 132kV network than the DNO anticipated. All the Outram staff I engaged with were extremely knowledgeable not only in the data loggers but also in their application. Outram Research downloaded and filed all the data in a logical manner mailing me the information. I have been so impressed with the company and staff that I recommended Outram Research Ltd to the Network Rail Power Quality department describing my experience with them. R H King.

Rob Weller04/02/2021Have used Outram equipment for a few years now, for power quality investigation work and G5/4 and G5/5 surveys etc. It is quality kit and with good analysis software. There is also a version capable of fault level monitoring. Most of all, a great company to deal with and fantastic support.Google rating score: 5.0 of 5, based on 7 reviews
