  • Patent number: 10140397
    Abstract: A computer-implementable method for simulating the electrical behavior of a surge arrester comprises providing a model of the surge arrester with a switchable current path between an anode and a cathode of the surge arrester, wherein the current path comprises a controllable voltage source. The current path is switched into the conducting or blocked state depending on a determined value of a voltage rise of an input voltage present between the anode and the cathode and a determined level of a response voltage. A level of the voltage of the controllable voltage source is set depending on a level of a current flowing in the current path.

  • Publication number: 20180171920
    Abstract: A piezo-driven fuel injector is modeled by measuring the actuation current and the actuation voltage of the piezo injector, transforming the actuation current and the actuation voltage into the frequency domain, forming a complex conductance from the actuation current transformed into the frequency domain and the actuation voltage transformed into the frequency domain, and determining one or more parameters of the piezo injector from the complex conductance. Once the complex conductance is determined it is used to detect a fault in the piezo injector.
