Electricity Grid Operators maintain a large amount of data that describes their built assets like power lines, transformer stations, or consumers and producers of electricity. Especially with the idea of having a "Digital Twin" of the grid, the amount of data is rapidly increasing over the last years. To assure high data quality, a lot of data testing needs to be performed. Examples for that are:
- datatypes need to be correct,
- numerical values need to be within reasonable boundaries (min max values),
- strings need to convey to regex patterns,
- quantities of the same assets need to be in reasonable ratios,
- coordinates need to be matching with adresses,
- and many more.
