Hardware and Software Functions of Standalone Field Data Acquisition Devices for the Low Voltage Power Distribution Grid
This paper is dealing with the data acquisition instruments, which are necessary nowadays for the optimal operation of low voltage power distribution networks. It introduces the requirements of data acquisition instruments, the proper choice of data acquisition time step and the solutions for real time placement of the acquired data. It describes the most common hardware architectures and the calculations that are fundamental for the usual software solutions of the data acquisition instruments. At last, it gives some practical advice to the application of data acquisition instruments. Keywords data acquisition, data processing, low voltage grid, microcontroller, communication
