Example Embodiment
[0046] A time synchronization method of a master-slave device, based on the completion of a time synchronization master station and a plurality of slave devices, and a satellite timing service device is set in the time synchronization master station; the time synchronization master station broadcasts a time synchronization command every T milliseconds, and the time synchronization command contains Current timestamp, time synchronization command received from the device. In this embodiment, T=120 milliseconds.
[0047] see figure 1 , This embodiment is a fault locating device for power distribution products: a transient recording type fault indicator. One of the core functions of this product is to record the ABC three-phase waves at the moment when the transmission line fails, and has a good effect on the three-phase synchronization. requirements, so that the master station can make fault judgment after receiving the waveform.
[0048] This product requires that the three-p...
