The project aims to develop a low cost, robust device which can detect and record both intermittent faults in wooden poles.
The project aims to develop a low cost, robust device which can detect and record both intermittent and peak faults in wooden poles on the network. The faults targeted are those whose current flow is not continuous and is generally not present when an operative goes to site to make a measurement, which makes fault finding difficult: Examples of this include:
The project will design and develop a laboratory prototype of the method and if successful, finalise the design and supporting information to enable further stages of development including field trials and preparation of the product for commercialisation.
The objectives and activities of the project are:
Stage 1: To develop and demonstrate a Laboratory prototype
Stage 2: Development of trial units and capture feedback on the design
Stage 3: To develop “large scale trial” units
Stage 4: Commercialisation support for the product
To create a method to identify fault current passage through poles is useful as it will reduce the area of inspection to small number of poles with indication of significant current flow.
At the end of the project a product will have been produced that when affixed to a pole will give real time indicators of earth current leakage. This will inform distribution network operators (DNO) operatives as to the environment into which they are entering prior to undertaking the work on the pole. At the same time DNOs will have a facility whereby they can communicate with the general public through a process of education that should the indicator be illuminated it is clear at the outset that the pole has been or is hazardous and should not be touched but reported for assessment by the DNO.
