    摘要: An earth leakage tester (300) generates a test signal for detecting an operation of an earth leakage detector (200) that detects an earth leakage current resulting from insulation resistance to earth from an output of a residual current transformer (3) inserted in an AC circuit (1). The earth leakage tester(300) includes a test signal generation portion(12) that generates, as the test signal, a signal having a same cycle as a voltage of the AC circuit and of which phases are switched selectively according to a wire system of the AC circuit. It is therefore possible to obtain an earth leakage tester(300) built into an earth leakage detector (200) that detects the earth leakage current resulting from insulation resistance to earth, an earth leakage circuit breaker equipped with the earth leakage tester (300), a circuit breaker (400), and an insulation monitor (500).

    摘要: A device, system, and method is disclosed for improving safety of a power system. For example, a differential current may be detected using at least one sensor by temporarily enabling sampling of current flowing through one or more conductors. Additionally, current flow may be temporarily altered in order to sample current in a system. The measurements may be handled locally and/or remotely and appropriate actions may be taken to enhance the overall safety of the system.
