摘要： A protective circuit includes a first jack, a second jack, a first control unit, a detecting circuit, and a logic control circuit. The first jack is connected to a power supply, and includes a grounding wire and a live wire. The second jack is connected to a load, and includes a grounding wire and a live wire. The first control unit includes a first relay, the first relay is connected to the live wire of the first jack and the live wire of the second jack. The detecting circuit detects whether the grounding wire of the first jack is grounded, and outputs indication signals accordingly. The logic control circuit outputs a control signal to the first control unit according to the indication signals to turn on/off the first relay, for allowing the live wire of the first jack to be connected to/disconnected from the live wire of the second jack.

摘要： Detecting a discontinuity or impedance irregularity in an active line, a neutral return line and/or an earth return path of a power distribution network is disclosed. In one aspect, the apparatus is configured to measure a change in voltage and/or current associated with a deliberate switching of a known impedance and/or a naturally occurring random switching of an impedance in the electrical network wherein the change in voltage and/or current flow results from a discontinuity or impedance irregularity in the active line, neutral line and/or earth return path. The apparatus includes an algorithm for identifying discontinuity or impedance irregularity in the presence of allowable variation in voltage and/or current that may mimic or hide a discontinuity or impedance irregularity in the active line, neutral return line and/or earth return path including a reverse current flow through the earth return path.

摘要： A fail check device and method for switching signal lines, wherein PWM signals are sent out onto PWM signal lines through a PWM signal output/survey circuit. Based on the level of the PWM signals to be sent out and the level of the PWM signals actually sent out, a PWM mismatch signal (logical) is produced. The produced PWM mismatch signal (logical) has a value which indicates a fault when the PWM signal lines are in a state of breakage or short circuit to a ground or the PWM signal lines in a predrive circuit are short-circuited to the positive wiring of a power source. Therefore, by using the PWM mismatch signal (logical), a breakage in the PWM signal lines or a fault in the predrive circuit can be detected by a control CPU.
