Objectives	The method proposed in the project is to implement an approach to provide continuous on-line fault level monitoring with three key components. 1. Active fault level measurement performed on the LV network of 11kV substations 2. Passive fault level measurement performed on feeders of primary substations 3. Correlation and verification techniques implemented to provide fault level monitoring across an entire radial network.The solution provider is Reactive Technologies (RTL). The solution builds up a picture of the fault level across an entire radial network beneath a grid supply point based on machine learning techniques. Due to the active measurement approach the high frequency of measurements allows for high accuracy and for fault level to be correlated between substations. This approach allows the solution to benefit from a larger scale of deployment. The technology has been developed in a laboratory setting and is subject to patent application. The next stage of development is to trial in an operational environment. The project is designed as a two-phase project each with its own clear aims and deliverables. The ultimate aim of this project is to provide a demonstration of the fault level monitoring technology on small sections of UK Power Networks network, to validate the commercial and technical benefits and establish a clear path to delivering a business-as-usual service as a result.Phase 1: Verification of RTLs fault level measurement against PowerFactory ModelThe validation technique will perform a parallel running of the existing power factory model and the new measurement technique. The PowerFactory model will output calculated fault levels which can be deemed as the true fault level in this exercise. The model will also output simulated COMTRADE files to be used as inputs in RTLs method to measure fault level. A comparison of the PowerFactory calculated fault level and the RTL measured fault level will provide verification of the technique. The deliverables of the validation study will be a report providing a quantitative comparison of the PowerFactory Model and RTLs fault level monitoring method.  Phase 2: Implementation of fault level measurement in a UK Power Networks study areaOnce the phase 1 method has been validated, the main aim for phase 2 is to demonstrate that the RTL fault level monitoring method can be deployed to measure fault level in the field. The main deliverable for phase 2 is proof of concept demonstration for a fully automatable approach to correlate and interpret fault level across the study area using continuous live monitoring. RTL will deliver a report to UK Power Networks which will detail the input data, assumptions, correlation and statistical analysis methodology. Supporting calculations will be included and the results will be presented clearly and concisely in an agreed format. Lastly there will be wider dissemination of the trial results, Foreground IP generated and replication strategies aligned to the NIA governance. The project aims to demonstrate and trial the RTL solution in order to prove that it is an accurate, scalable and cost effective model of deploying fault level monitoring at sites where fault levels have exceeded 95% allowable limit, as estimated by PowerFactory.
