Objectives Phase 1 - Sensor System Design Programme - 4. 5 months: This phase will involve the design and simulation, and production of a bill of materials, of the prototype optical sensors. This work will be in accordance with the sensor specifications detailed by IEC standards and in line with the expectations of theproject’s stakeholders. Synaptec will liaise with manufacturers of piezoelectric elements - a crucial component in the design of the sensors - in order to rigorously evaluate which materials exhibit an optimum balance between responsiveness and robustness to fluctuating outdoor environmental conditions. The design and simulation activity will ensure that assembled transducers shall be packaged and insulated appropriately for conditions in the target environment. Phase 1 DeliverablesD1. 1 Design / packaging specificationD1. 2 Bill of materials for transducers Phase 1 MilestonesM1. 1 Functional and physical specification of transducers completedM1. 2 Transducer design and simulation completed Phase 2 - Sensor Construction and Initial Testing - 4. 5 months: This phase will involve the assembly and testing of prototype sensor elements. This task will be managed by Synaptec, who will work with the University of Strathclyde and the sub-contractor Optocap Ltd to produce packaged sensors based on the designs produced in Phase 1. Assembly will be carried out primarily by Scottish optical packaging company Optocap Ltd, with intermediate testing performed at Synaptec’s facilities throughout the assembly procedure. This phase will ensure transducers are packaged and insulated appropriately for the target environment, and have the potential to progress into commercial manufacturing at the project conclusion.

Abstract In the future, increased electricity demand and moves from large-scale centralised generation towards large penetrations of renewables will present challenges to monitoring, protection and control functions. There is an increasing requirement to "observe" the system more extensively in real-time and for faults to be dealt with more effectively (e.g. minimising further the removal of healthy system elements, requiring more measurement and isolation points) and with minimum delay (e.g. to preserve stability in "weaker" power systems). Protection of future transmission and distribution systems will present challenges, exacerbated by the fact that existing protection is largely based upon single measurement points located sparsely throughout the network. Synaptec Ltd is developing a unique technology (confirmed 07/2014 by UK IPO audit) which allows any standard telecommunication fibre to be utilised to measure a broad range of electrical and environmental parameters. These include voltage, current, vibration, temperature (ambient or surface), strain, and pressure, with only a single fibre needed to acquire all measurements (potentially 100 discrete sensors per fibre). The type of optical sensing element utilized are well-established in military and structural health monitoring applications due to their small size, light weight, EMI-immunity, and their ability to be multiplexed in high numbers along a single optical fibre. This innovation provides geographically-distributed measurements of current, voltage, vibration and temperature at a single interrogation point; enabling faster, more selective protection and enhanced monitoring of network conditions. The project will perform development work to progress the technology towards a field trial at 132 kV or above (candidate site identified) demonstrating multi-sensor operation integrated with existing Current Transformer (CT) and Voltage Transformer (VT) secondary circuits. The technology has a unique potential to drastically reduce network operators’ costs by eliminating conventional infrastructure expenditure associated with instrumentation for monitoring, control and protection. In certain applications, this technology may be able to cut costs by as much as 80% while minimising the ongoing maintenance and management of protection and measurement components. The technology is also capable of underpinning advanced network-wide monitoring and controls by providing a mechanism for the efficient and extensive instrumentation of the network at all voltage levels.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
