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

Abstract

There is much discussion about the implementation and benefits of smart electricity networks. However, the reality is that the instrumentation needed at low voltage is 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 used on single-phase cables and terminations at £1k–£2k per substation. This study presents the results of novel research into modelling and analysis of a low-cost sensor which can measure load on a 3 core cable at
