In this paper we focus on improving the tests coverage of a Schneider Electric protection device using system modeling and simulation techniques. Our approach consists of modeling the device in its operating environment: Timed Transaction Level Models (T-TLM) for the digital parts, Matlab waveforms for the analog parts, and scripting language for the tests automation. This approach is applied on a medium voltage protection relay called Sepam10. This example is considered to be typical for a wide class of protection and safety devices at Schneider Electric, thus showing that the modeling approaches used in high complexity System On Chip (SoC) devices are also of great interest for power electronic control devices.
