  • Patent number: 10446340
    Abstract: In aspects, the present invention provides a method for controlled energizing of a transformer (150) being connected to a first electrical subsystem (110) through a first circuit breaker (140). The method comprises acquiring electrical current waveform in a first phase of the transformer during a closing operation of the first circuit breaker at an instance for switching determined by a controller (130), determining a first peak (310) in the current in the first phase within a first predetermined time window (Tpw), calculating a first correction factor for adjusting the instance for switching in the first phase, and adjusting the instance for switching based on the calculated first correction factor for performing a next controlled energization at the adjusted instance of switching in the first phase.

  • Patent number: 10438757
    Abstract: The present invention provides a method of determining an electrical operating time of a circuit breaker (140) in a multiphase electrical system having a subsystem (160) at an electric potential resulting from electrical characteristics of electrical components within the subsystem. The method comprises monitoring (145) the voltage of the subsystem in the first phase, determining a first rate of change from the monitored voltage in the first phase, detecting at least one instance of switching based on the first rate of change, determining an electrical operating time of the circuit breaker based on the detected at least one instance of switching and an instance at which a command for switching was provided to the circuit breaker.

  • Patent number: 10074494
    Abstract: A method is disclosed of performing point on wave switching in a multiphase electrical system having a first circuit breaker connected a first bus, the first circuit breaker being operated by a first controller, a second circuit breaker connected to a second bus, the second circuit breaker being operated by a second controller, and a subsystem transferred from the first bus to the second bus. The method can include receiving, by the second controller, system characteristics data of the subsystem, estimating, by the second controller, a time for switching based on the received system characteristics data of the subsystem and operating time of the second circuit breaker, and operating, by the second controller, the second circuit breaker at the estimated time for switching, for switching the subsystem.
