摘要： A high voltage pulse generator provides a short, fast rise, high voltage pulse from a very low impedance suitable for initiating high energy electrical discharges in liquids and high pressure gases. Its low impedance allows extremely high currents from external energy storage capacitors to be conducted through the invention once the invention has initiated an arc. Its fast rise time is suitable for initiating multiple arcs or even sheet surface discharges in high pressure gasses under suitable conditions.

摘要： A pulse signal generator comprising a magnetic element able (1) to cause a large Barkhausen jump; a detection member (2) for detecting a magnetic change in the magnetic element to generate a pulse signal; and a pair of magnetic field sources (3, 4, 6, and 7) provided in parallel to each other on both sides of the magnetic element such that their poles (3A, 4A) are opposed to each other so that when an object (5A) advances from one of opposite poles to the other of the magnetic field sources, a magnetic field applied to the magnetic element changes, causing a large Barkhausen jump in the magnetic element, thus causing the detection member to generate a pulse signal.

摘要： The system includes a plurality of voltage transformers in a protective relay for A, B and C-phase power system voltages, responsive to the secondary windings of corresponding voltage transformers for the power system, the secondary windings of the voltage system power transformers being connected in a broken delta arrangement. The primary windings of the relay voltage transformers are arranged in a broken delta configuration and connected to the secondary windings of the power system voltage transformers so that A-phase, B-phase and C-phase voltage are provided at the secondary windings of the relay voltage transformers. The three-phase voltages may then be summed to produce a residual voltage value.

摘要： The invention includes a transformer for converting three-phase AC power to nine-phase AC power. An autotransformer includes three coils, each coil including a plurality of serial windings that together form a polygon. Nine output nodes are provided between adjacent winding pairs, the windings sized and arranged such that adjacent output voltages are separated by 40 degree phase shift and such that output voltage magnitudes are essentially identical. Both step-up and unity gain input node sets are provided wherein, when three phase AC supply lines are linked to the step-up input set the output voltage is stepped up and when the three phase AC supply lines are linked to the unity gain input set the transformer gain is unity. An isolation transformer includes a secondary arranged like the autotransformer configuration described above.
