How Power Survey Works

During the survey process, Osmose's truck-mounted Power Survey MAAV technology scans the target area to detect low-level electric fields emanating from structures that have been energized due to an underground fault. It simultaneously detects voltage on all surfaces in an area: streetlights, manholes, fences, roadways and pavements.

During the field measurement process, alerts from the MAAV are investigated using handheld measurement equipment. Route coverage data is collected automatically, and a 'qualified reference' is used for the voltage and harmonics content measurements for each structure. Osmose provides relevant data via a 24/7 despatch centre, stand-along or integrated into existing GIS and work management systems.

All data and photos of the detected identified and monitored energised object and qualified references are recorded in the GridSight diagnostic service and presented in event reports of stray and/or contact voltage that is hazardous to humans and animals. Event reports are delivered in real time.
