    摘要: An apparatus for testing the life of a leakage current protection device having a leakage current detection circuit and a trip mechanism. In one embodiment, the apparatus includes a ground fault simulation circuit for generating a simulated ground fault during every negative half-wave of an AC power, a signature signal generating circuit for generating a signature signal reflecting the characteristic of the leakage current detection circuit and the trip mechanism, when the simulated ground fault is generated, and a life testing detection control circuit having a microcontroller and an alarm circuit. In operation, the life testing detection control circuit receives the signature signal from the signature signal generating circuit, analyzes the received signature signal to determine whether at least one fault exists in the leakage current detection circuit and the trip mechanism, and activates the alarm circuit if the at least one fault exists.

    摘要: An apparatus for testing the life of a leakage current protection device, comprising a microcontroller unit, at least one of a first fault detector and a second fault detector, at least one of an audio alarm and a visual alarm, a power supply circuit. In operation, the first fault detector and/or the second fault detector receive at least one signal from the leakage current protection device, and generate at least one DC voltage corresponding to the at least one signal to be received by the MCU. The MCU compares the at least one DC voltage with a predetermined threshold value to determine whether a fault exists in the leakage current protection device, and activates the alarm circuit if at least one fault exists.
