    摘要: A method of locating a fault on an electrical network energized by a source uses a form of triangulation of voltage measurements at at least three different locations on the network, with at least one of the locations situated upstream from the fault with respect to the source. Voltage phasors corresponding to the voltages measured during the fault are time synchronized. Conductors of the network involved in the fault are determined as a function of characteristics of the voltage phasors and a fault current causing a voltage drop at one of the locations with respect to an initial voltage value is evaluated. A position of the fault is evaluated at a point of the network where a ratio between a difference of the voltages measured at two of the locations and an impedance between one of the two locations and the point is equal to the fault current.

    摘要: A self-powered self-contained electrolysis device, for placement into a reservoir of a contaminated electrolytic solution, such as water, containing halide ion, such as chloride ion, to electrolyze the water, thereby disinfecting or sterilizing the contaminated reservoir of water. Contaminated reservoirs of water can be water containers filled with river water and other outdoor sources, or can be contaminated municipal water held in kitchen containers, cooling systems, water tanks, cisterns, etc. The self-contained body allows the electrolysis device to float on or remain self-contained in the reservoir water. Preferred devices are small and portable, and comprise reliably productive electrolysis cells that are powered by batteries. A means for propulsion of the device can also be provided, and is preferably a pump that pumps the water through the electrolysis cell.
