Abstract: Methods and systems detect short circuits in an electrical system, such as a dynamic braking grid of a vehicle. The methods and system measure a characteristic of a current that is conducted through one or more resistive elements of an electrical system. The current is supplied to the electrical system from a power source as an applied voltage. A resistance change signal representative of a change in one or more electrical resistances of the one or more resistive elements is determined The resistance change signal can be based at least in part on a difference between the characteristic of the current that is measured and a low pass filtered value of one or more of the characteristic of the current that is measured or the applied voltage supplied by the power source. A short circuit event is identified based at least in part on the resistance change signal.

Abstract: A current differential protection system for a multi-terminal power line includes a current sensor for sensing a current at a local terminal, a controller for time synchronizing the local terminal and remote terminals, and a fault detection module to detect a fault in the multi-terminal power line if a differential current exceeds a threshold value. The controller includes a time measurement exchange module for exchanging time stamp data with remote terminals, an upper range clock for exchanging time stamp data with remote terminals and a lower range clock for indexing the current at the local terminal. A first time period of the upper range clock is N times a second time period of the lower range clock where N is a number of multi-terminals. The controller includes a clock offset calculation module for determining an average time offset based on time stamp data from remote terminals and the local terminal.

Abstract: A flexible transformer system includes conductive windings extending around a magnetic core of a transformer phase and impedance-varying windings extending around the magnetic core of the transformer phase. The conductive windings and the impedance-varying windings are configured to conduct electric current around the magnetic core of the transformer phase. The system includes an impedance switch coupled with the impedance-varying windings and with the conductive windings. The impedance switch is configured to change an impedance of the system by changing which impedance-varying winding of the impedance-varying windings is conductively coupled with the conductive windings and which impedance-varying winding of the impedance-varying windings is disconnected from the conductive windings.

Abstract: The DC leakage current detector for detecting leakage current in a DC bus includes a pair of transformers each comprising a magnetic core and excitation and detection windings would about the magnetic core, with the magnetic core positionable about a pair of conductors that create a magnetic field that is a sum of currents in the conductors. An excitation and biasing circuit is connected to the excitation winding in each transformer to inject a current signal thereto that creates a changing magnetic flux in the core of each transformer and a detector output connected to the detection winding in each transformer to receive a voltage therefrom generated responsive to the magnetic flux in the core of each transformer, wherein the voltage on the detection windings provides a net voltage at the detector output whose value is indicative of a presence of a leakage current on the DC bus.
