1. Evaluate SASensor’s ability to perform under a variety of fault conditions (10 system faults). 2. Proof of stability for faults beyond the first pole mounted recloser and proof of clearance for faults close into Primary substation (10 system faults). 3. Identification of fault current on individual feeders when faults occur. 4. SSE Power Distribution to improve understanding of commercial and technical aspects of system deployment (installation, design, commissioning and maintenance) with existing practices. 5. Evaluate the event recorder data to see if proactive maintenance of switchgear can be performed via condition based monitoring. 6. Evaluate system for business roll out. In response to each objective: 1. Perform post-fault analysis on waveforms captured by the SASensor system on site. 2. As number 1. 3. Post fault analysis on 10 system faults. 4. Note points during the development and installation where improvements could be made and discuss with Locamation. Determine full costs of both systems, and evaluate with pros and cons. 5. Desktop based report on the costs, time and training required. 6. Desktop based report on this new technology versus our existing range of protection systems.

Current policy is to use individual relays to protect the power system from faults. This leads to vendor lock in as well as entrenching systems that are not flexible or interoperable. The proposed project uses a digitised approach where a single processing unit protects the entire substation. It also gives remote access to fault information, which may assist in a reduction of customer minutes lost during power cuts, and provides information which can be used to determine whether maintenance of plant and equipment is required. The project involves a UK deployment of the Locamation HMV SASensor solution which has been successfully deployed in the Netherlands. This system uses a digital approach to protection and control of our substations, giving a central hardware processing approach in contrast to the individual relaying approach we currently practise. This system will allow us to connect remotely to the system to retrieve fault and maintenance information, and allow for remote programming of settings, reducing the need to travel to site, and improving the overall network for our customers.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
