Reliable and efficient distribution within these power grids will continue to depend on the development of lighter and more efficient sensing units with lower costs in order to measure current and detect failures across the grid. The objective of this paper is to present the development of a miniature piezoelectric-based sensor for AC current measurements in single conductors, which are used in power transmission lines. Additionally presented in this paper are the thermal testing results for the sensor to assess its robustness for various operating temperatures.en2076-08252014162181Multidisciplinary Digital Publishing Institutehttps://creativecommons.org/licenses/by/3.0/AC current sensorpiezoelectric sensornon-intrusive sensorPZTbimorphforce on a magnetAC magnetic fieldsmart gridIngenieurwissenschaftenJournal Article2019-03-29urn:nbn:de:gbv:830-882.02958910.15480/882.216610.3390/act303016210.15480/882.2166Journal Article
