Live Alert proposed a new project to develop a vehicle mounted warning system that would alert any person nearby by audible and visual indications that the vehicle has become live. It is envisaged that the system would be fitted to a range of vehicles used by OHL teams and other field staff exposed to live working. The system would warn users of the vehicle not to approach if, for example, a broken conductor fell onto the vehicle and it has become energised with respect to earth. The system is effectively a voltage alarm that can sense when its electrical potential exceeds a preset limit and operates without any connection to earth, it has a self contained test facility to confirm its operation before use and an internal data logger.
The project is split into four stages as follows;

  • Design and develop a new sensing system and power inverter

  • Design and develop a refined prototype incorporating the new sensor and power supply

  • Manufacture 10 units for on site evaluation

  • Implementation of Pilot/Simulation exercise.

The final deliverable will be a plastic / metal enclosure, approximately 200 x 100 x 100mm in size that has sockets to enable the connection of external power, external audio amplifiers for warning, external warning lights and a USB connection for downloading the past recorded incident data. The project will deliver ten prototypes for full testing and evaluation.
