Abstract
This paper discusses the performance and functionality of the combination of Low-power stand-alone sensors and IEDs. For the first time in MV applications, we report testing performed on the combination of sensors and IEDs with digital output according to the IEC 61850-92LE format. Accuracy measurements performed on prototypes show high promise both for metering and protection applications. The influence of cable lengths up to 100 m on the accuracy of existing sensor products in combination with new IEDs is discussed and good performance for protection functions like differential protection is proven.
