Promising First Trial Results for Outram Fault Level Monitor

RMS Fault Level 90ms After Fault

In this issue of Outram News we talk about the very encouraging initial results achieved by our new fault current prediction technology in trials with ScottishPower. We also highlight our Hook-up Checklist – just one of the ways Outram Research is working to give you the best possible service and support – and we welcome Kate Edwards to the team.

Encouraging results delivered by initial FLM field trials with ScottishPower

Developed by John Outram, Managing Director of Outram Research, our new fault current monitor, the FLM, has delivered very promising results from initial trials with ScottishPower. During the first stage of the trials, in which RMS ‘break’ current was measured using results from the network, our result for peak fault level was within 2% of the calculations from the network model.

Accurately predicting the peak fault current on their networks is critical to electrical utilities as, for instance, it makes the rating of circuit breakers an easier task. With the increasing amount of renewable regeneration coming onto the grid, which by its very nature cannot all be predicted and modelled, to have an instrument which can observe and predict the real worst case fault level is an exciting proposition.

The peak fault current defines the rating of the components such as circuit breakers required to ensure that they can safely withstand the large release of energy that occurs during an electrical fault. So when the FLM research is complete and the monitors are rolled out, utility companies will hopefully be able to specify their network components better and save money (tens or hundreds of thousands of pounds at a time) through not having to change or over specify components to play safe.

Have you seen our New PM7000 Hook-up Checklist?

Make setting up your PM7000 analyser quick and easy with our new Hook-up Checklist. Illustrating the ten hook-ups pre-configured in the PM7000, the Checklist gives full instructions, diagrams and pictures of the physical connections needed to ensure you get the data you require. This booklet also displays the corresponding images you will see on PMScreen and explains what they mean.
