Power systems are facing fundamental changes concerning functionality and dynamics today. However, detailed data of the system are property of the suppliers or distributors and are not easily available to researchers at present. In order to understand the system dependencies we propose to derive state information by combining high-rate low-voltage time series captures at different locations together with a simulation model of the grid. We take the island network like KIT campus as our starting investigation site. In a first step we developed the Electrical Data Recorder (EDR), which is capable of recording three phase voltage time series at up to 25 kHz synchronously. All data are stored in a large scale database facility (LSDF) for subsequent usage. We intend to derive a simulation model from the comparison of the voltage characteristics to periodic smart meter measurements as the indication of the load status. In this article we introduce the new recording device and present first results.
