    • MUs and IEDs are included. Each of the IEDs includes a signal control unit that derives the time difference between the sampling timings in the MUs on the basis of digital data from one end of a protection area and digital data from the other end of the protection area, controls the cycle of a sampling-timing control signal to eliminate this time difference, and outputs this controlled sampling-timing control signal to a merging unit corresponding to each computation unit. Each of the MUs includes a control-signal output circuit that generates a sampling signal synchronized with the sampling-timing control signal from the IEDs and outputs this sampling signal as a control signal, and a data output unit that converts an electrical input to digital data and outputs the digital data.

    • Power distribution systems and methods are described. In one example, a method of determining by a first circuit protection device in a zone selective interlocking (ZSI) system whether to output a blocking signal to a second circuit protection device in the ZSI system is described. The method includes detecting, by a current rate of change sensor, a rate of change of a current flowing through the first circuit protection device. A trip unit receives a current rate of change signal from the current rate of change sensor. The current rate of change signal is proportional to the detected rate of change of the current flowing through the first circuit protection device. The trip unit determines whether to output the blocking signal to the second circuit protection device based, at least in part, on the current rate of change signal.

    • A current differential relay comprises: an interface section; a quantization section; a communication section; and a difference calculation section. The quantization section quantizes current received by the interface section and converts it to first current data. The communication section, in the case where this relay is a representative current differential relay of a first group, transmits second current data from another current differential relay belonging to the first group and the first current data jointly to a representative current differential relay belonging to the second group, receives third current data from the representative current differential relay, and transmits the third current data to the other current differential relays. A difference calculation section executes a current difference calculation based on the first to third current data.

    • A ground-fault circuit-interrupter (GFCI) system is provided that provides reliable and timely tripping of faulted circuits while minimizing so-called “nuisance” tripping. The GFCI includes a voltage unbalance detection device coupled to the main bus circuit for detecting a voltage unbalance during a fault condition. A computer processor in communication with the voltage unbalance detection device is programmed to determine when an actual fault condition exists based on a state of the voltage unbalance and certain predetermined among the fault signal generated by a GFCI unit in the main bus circuit and the fault signals generated by GFCI units in individual feeder circuits.
