Generator Circuit Breakers (GCBs) are commonly used in electrical power generation systems to protect key equipment such as transformers and generators from damage due to overload or short-circuit. However the interruption and feeding of high currents lead to the ablation of the electrical contact system of the breaker. This deterioration process needs to be monitored in order to guarantee the healthy...
This paper focuses on the electro-thermal modeling of an electrical current sensor, based on the Rogowski Coil transducer. We exploit the multi-domain capabilities of VHDL-AMS together with geometrical Finite Element Analysis (FEA) to create a time-dependent parametrical model which is able to compute concurrently the thermal and electrical variables of the system. This is particularly convenient...
An electro-thermal model of a Rogowski Coil sensor system is here described. A co-design methodology between VHDL-AMS and Finite Element Analysis (FEA) has been used for modeling the entire system. The proposed modeling strategy uses geometrical FEA to complete a time-dependent parametrical heat transfer model, which can be implemented in VHDL-AMS or in any other similar hardware description language...
