Fault location system PH series

PH series travelling waveform fault locating relay/equipment test set is a new device to meet the needs of testing and verification for travelling wave fault location equipment and protection relay with TWFL function. PH series travelling wave fault location test set is with three-phase wide bandwidth, high-speed current output channels so that it could playback the complete travelling wave fault signal with high quality. The software owns fault playback function, which can output either the corresponding traveling wave signal according to the EMPT simulation waveform data of the power system fault current traveling wave or the recorded travelling waveform data from the substation or any other actual field testing. Meanwhile, the software supports reading and editing the Comtrade format data file. Also, the customized auto-test software which could support to create and playback user defined waveform is optional to facilitate calibration purpose in laboratory. PH series for Travelling Waveform fault location test could finalize the verification of 2 travelling-wave fault location equipment/protection relays in 2 different location with long-distance transmission by time-synchronization with GPS accessory which could work together with PH series verification platform. By output the travelling-wave waveform file via D/A and current/voltage channels, PH series verification platform can be used for simulating travelling-wave fault signal to output into the equipment to be tested. In this way, the travelling-wave fault indication equipment could receive the fault signal and calculate the result, such as fault location point and distance
