Textile‐based sensors for electrical current measurement in three‐phase cables

There is much discussion about the implementation and benefits of smart electricity networks. However, reality that instrumentation needed at low voltage too expensive for large-scale deployment. The most highly used monitoring systems in use today are based on Rogowski coil technology, which can only be single-phase cables terminations £1k–£2k per substation. This study presents results novel research into modelling analysis a low-cost sensor measure load 3 core cable <£150 uses new textile-based produced by low-cost, high-volume manufacturing techniques. describes required conjunction with geometry to able calculate current. Three sensors different dimensions were tested compared current probe readings. shows textile have an offset error 14% but good linearity 0.998, around 10% cost technology.
