  • Patent number: 10192677
    Abstract: The present invention comprises an apparatus and method for detecting a loss of oil from an oil-immersed transformer, based on fitting a transformer top-oil temperature model to online measurements in an iterative optimization process that yields fitted values for a first model parameter representing the top-oil temperature rise over ambient temperature and a second model parameter representing the oil time constant. Among the several advantages seen in the contemplated apparatus and method is the reduction in required instrumentation, whereby transformer oil leaks are indirectly detected without requiring pressure sensors or mechanical floats, although the presence of such sensors is not excluded by the teachings herein.

  • Patent number: 9874593
    Abstract: A decision support system is provided for utility operations to assist with crew dispatch and restoration activities following the occurrence of a disturbance in a multiphase power distribution network, by providing a real-time visualization of possible location(s). The system covers faults that occur on fuse-protected laterals. The system uses real-time data from intelligent electronics devices coupled with other data sources such as static feeder maps to provide a complete picture of the disturbance event, guiding the utility crew to the most probable location(s). This information is provided in real-time, reducing restoration time and avoiding more costly and laborious fault location finding practices.

  • Publication number: 20170030958
    Abstract: According to an embodiment of a power network device, the device includes a computer configured to estimate a plurality of parameters internal to a transformer, including estimating a turns ratio of the transformer. The computer performs the parameter estimation based on an equivalent circuit model of the transformer and current and voltage samples which correspond to current and voltage measurements taken at primary side and secondary side terminals of the transformer. The computer indicates when one or more of the estimated parameters deviates from a nominal value by more than a predetermined amount. The computer can be part of an intelligent electronic device configured to acquire analog or digital signals representing the primary side and secondary side current and voltage measurements, or located remotely from the intelligent electronic device e.g. in the control room or substation controller.
