Low Cost Current Measurement Of Three Phase Cables

Recent growth in embedded generation alongside the anticipated consumer uptake of electric vehicles (EVs) and heat pumps present new challenges for distribution networks. This includes greater fluctuation in electricity demand. Data from existing maximum demand indicators in distribution substations is inadequate to understand the spread of demand over time. Retro-fit datalogging solutions are available for substation monitoring, but cost typically >1200 pound, which would be difficult to justify for all distribution substations. This paper looks at the development of a novel low cost alternative designed for measuring load on three phase cables.
