  • What is a fault and what are the different types? - USGS

    A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers. Most faults produce repeated displacements over geologic

    A circuit breaker is an equipment which can open or close a circuit under all conditions viz. no-load, full load and fault conditions. It is so designed that it can be operated manually (or by remote control) under normal conditions and automatically under fault conditions. For the latter operation, a relay circuit is used with a circuit breaker.

  • US4996624A - Fault location method for radial transmission

    A method of locating a phase-to-ground fault in a radial distribution system with a tapped load. The method includes determining the positive-sequence impedance from the residual current, the residual current compensation factor and the phase-to-ground voltage of the faulted line. The positive-sequence impedance is then used to determine the distance to the fault.
