  • TRANSFORMER DC MAGNETIZATION DETECTION AND MITIGATION THROUGH VIBRATION MEASUREMENT
    Publication number: 20250111989
    Abstract: The present disclosure relates to a method for detecting a DC magnetization in a transformer and controlling the transformer, the method including: sensing, using at least one vibration sensor, at least one vibration on at least one surface of the transformer or on at least one surface of a component connected to the transformer; measuring the sensed at least one vibration; detecting, based on the measured at least one vibration, the DC magnetization in the transformer; and controlling, based on the detected DC magnetization, the transformer. The present disclosure also relates to a respective device and system.

  • Bypass thyristor device with gas expansion cavity within a contact plate
    Patent number: 11139219
    Abstract: A bypass thyristor device includes a semiconductor device providing a thyristor with a cathode electrode on a cathode side, a gate electrode on the cathode side surrounded by the cathode electrode and an anode electrode on an anode side; an electrically conducting cover element arranged on the cathode side and in electrical contact with the cathode electrode on a contact side; and a gate contact element electrically connected to the gate electrode and arranged in a gate contact opening in the contact side of the cover element; wherein the cover element has a gas expansion volume in the contact side facing the cathode side, which gas expansion volume is interconnected with the gate contact opening for gas exchange.
