摘要： An assembly for interfacing an existing harness connector of an installed wiring harness to a test module. The assembly comprises: a harness-specific connector which is connectable to the existing harness connector, a test box connector module connected to the harness-specific connector, for connecting to a test module, and a unique identifier which is readable on the assembly and which is unique to the test box connector module; wherein the unique identifier is used to identify the test box connector module and to determine, from a list of unique mate-in interface IDs and associated connector configurations, which one of the associated connector configurations corresponds to the identifier of the assembly, and within the one of the associated connector configurations corresponding to the unique mate-in interface ID of the mate-in interface, to determine the correspondence between contacts of the test module to contacts of the existing harness connector.

摘要： A method and a device for improving current transmission reliability are provided. The method includes: selecting effective points; performing technical measurement; generating a threshold: generating a critical abnormal alarm time threshold t1, generating a critical defect alarm time threshold t2, and generating a non-critical abnormal electric leakage threshold t3; and generating a necessary remaining life number Δt21, wherein Δt21=t2−t1. By judging whether a current carrying capacity passing through an electric transmission line portion at a certain time exceeds an allowable current carrying capacity, the alarm time threshold t1 is far lower than 20%, an alarm is capable of being given for an abnormal situation in time, and a necessary remaining life of an electric device or system can be predicted by randomly measuring an input current Iin i, an output current Iout i, and errors of input and output currents, so that cross liability is avoided.

摘要： A processor receives an indication of a fault from a first isolation device. The processor sends a first open command to a downstream isolation device downstream of the fault, identifies a tie-in isolation device, and identifies a line section without current monitoring positioned between the tie-in isolation device and the downstream isolation device. The line section has a plurality of line segments, each having a load rating. The processor receives incoming and exiting current measurements for the line section and estimates a first current load for each of the line segments in the line section based on the incoming and exiting current measurements and the load ratings. The processor selects an intermediate isolation device between the tie-in isolation device and the downstream isolation device based on the first current loads, sends a second open command to the intermediate isolation device, and sends a close command to the tie-in isolation device.

摘要： A fault isolating device for use in a microgrid disconnected from a main power grid includes a voltage meter for detecting a voltage anomaly indicative of an electrical fault, a timer for establishing a time window that begins and ends a predetermined time after a voltage anomaly is detected, a switch that is opened at the start of the time window, and a microcontroller that determines whether to leave the switch open to isolate a faulted portion of the microgrid or to close the switch. A plurality of fault isolating devices can be distributed throughout a microgrid to isolate a faulted branch or faulted branches of an islanded microgrid without interfering with normal fuse operation when the microgrid is connected to the main power grid.

摘要： Systems, methods, and computer-readable media are disclosed for high impedance detection in electric distribution systems. An example method may include calculating, by a processor, a relative randomness of a signal, wherein the relative randomness is a derivative of a first scale wavelet transform divided by an energy of the signal. The example method may also include calculating, by the processor, one or more scales of a wavelet transform of the signal. The example method may also include calculating, by the processor, one or more energy ratios between energy of the wavelet transform in the one or more scales. The example method may also include calculating, by the processor, a zero-crossing phase difference between a third harmonic and a fundamental component of the signal. The example method may also include determining, by the processor, that a high impedance fault occurs based on at least one of: the relative randomness, a comparison between the one or more scales of the wavelet transform, and the zero-crossing phase difference.
