VisNet from EA Technology has launched VisNet View, a compact, pole-mounted monitoring device designed specifically for overhead low-voltage (LV) networks.
With approximately 250,000 pole-mounted substations across the UK, all of which transfer power directly to homes and businesses, it’s vital that asset owners have a clear picture of their network.
VisNet is the first UK based business to develop the technology, with the View delivering unparalleled grid-edge intelligence to Distribution Network Operators (DNOs).
While some existing overhead LV monitoring technologies measure purely the aggregated values at the pole-mounted transformers, the View provides grid-edge intelligence at feeder level, granting overhead LV asset owners’ access to real-time, detailed insights network wide, supporting future capacity management and improved reliability for customers, with particular benefit for vulnerable households, in previously hard-to-reach areas.
Data collected by the VisNet View includes phase and neutral currents per phase, phase to neutral voltages, real, and reactive power per phase and transformer, along with apparent power at the transformer, total harmonic distortion for voltage and current measurements, pole angle changes, and pre-fault and fuse blow events – all of which can be viewed via VisNet’s Detect Pro UI.
Overhead LV asset owners and operators can then visualise and interrogate the data processed at the grid-edge, allowing them to prioritise repairs, reduce unnecessary engineer call outs, and identify assets that require preventative maintenance.
Mark McManus, Head of Monitoring at VisNet, said, “Building on the success of the other VisNet devices, which now occupy approximately 1 in 8 UK ground-mounted substations, we’re very excited to launch the View to bring actionable insights to the overhead LV lines.
“It’s an asset that will provide owners and operators of LV networks with extensive grid-edge intelligence to support well-informed operational decisions, detect future capacity challenges and plan maintenance investment more effectively.
“As the overhead network becomes increasingly complicated with the addition of bi-directional energy flow, visibility is key.
“Grid-edge intelligence is all about helping DNOs keep Britain’s lights on, and with the View, we’re helping them to deliver a better service to their customers whilst supporting the UK’s decarbonisation goals.”
Traditionally, these LV networks only distributed power to consumers, but given the rapid adoption of low-carbon technologies such solar panels and EVs, this means they are now also expected to support exporting capabilities as well.
As a result, overhead LV assets are under additional strain, and monitoring the network is playing an increasingly critical role in maintaining these networks as they adapt to widespread electrification and the decarbonising world.
