  • Patent number: 11525850
    Abstract: A method and an apparatus are presented which enable the identification of a capacitor fault in a given string of a capacitor bank, based on the computation of the string impedance by measuring the string AC current and voltages, where each string includes a plurality of capacitor elements connected in series. The method consists of measuring the string capacitive impedance and comparing this value with a previously measured capacitive impedance of the same string. If a difference between these two values is obtained, which exceeds a given threshold for a certain duration, a fault is recorded.

  • Publication number: 20200241060
    Abstract: A method and an apparatus are disclosed for providing an indication of a capacitor fault in a given string of a capacitor bank comprising at least one string mounted in parallel, each string comprising a plurality of capacitor elements connected in series. The method comprises obtaining a capacitor bank voltage, the obtaining comprising measuring a voltage across the capacitor bank; obtaining a current of the given string, the obtaining of the current of the given string comprising measuring a current flowing in the given string of the capacitor bank; determining a measured impedance at a grid frequency using the obtained capacitor bank voltage and the obtained current of the given string; providing an indication of a capacitor fault if a difference between the measured impedance and a previously measured impedance exceeds a first given threshold for a first given duration.

  • Publication number: 20050134886
    Abstract: The invention generates a page description language compliant data stream, that has been pre-designed and pre-processed to create unique and predictable page element ordering, overlay layout, and for splitting large page elements into multiple independent elements. In this way, multiple processors can be used to render the document without merging the data stream.
