Product Introduction PH Series Travelling Wave Fault Location Test Kit is a new device to meet the needs of testing and verification for travelling wave fault location equipment PH Series Travelling Wave Fault Location Test Kit 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 tester 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 testings.Meanwhile, the software supports reading and editing the comtrade format data file. Also, the customzied auto-test software which could support to create and playback userdefined waveform is optional so as to facilicate calibration purpose in laboratory. PH Series Travelling Wave Fault Location Test Kit could finalize the verification of 2 travelling-wave fault location equipment in 2 diiferent location with long-distance transmission by time-sychronization with GPS accessory which could work together with PH series verification platform. By output the travelling-wave waveform file via D/A and current 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, and then compare with the result of original file to verify if the equipment test, is with correct reaction or not. Software Introduction • Support playback Comtrade file and download the file into the PH's hardware to output the fault signal into the equipment to be tested • Support to select different data content in each channels in Comt rade files • Support to adjust the amplitude of each current output channels • Support to define the output range before playback the comtrade file by setting pre-fault time and extension multiplier

Engineering Applications The technicians of PONOVO used the PH series travelling wave fault location tester in the double-end joint adjustment test of the travelling wave fault location device of Debao Line (Deyang to Baoji), and found the test results and the theory issued by the tester. The inherent error of the traveling wave signal is 4000m, and the triggering time of the double-ended traveling wave head is different from the theoretical value by 13us. The analysis by the on-site commissioning personnel is due to the error caused by the different types of timing GPS in Deyang and Baoji....

On April 14-17, 2012, the operating branch coordinated on-site maintenance personnel, Shandong Kehui Company, PONOVO and ABB in Fulong Station and Fengxian Station to conduct single-ended and double-ended test on the Kehui XC-2000, in accordance with the requirements of the State Grid technicians, combined with the highimpedance grounding phenomenon that has occurred on the site, the technicians of our company used the PH series travelling wave fault location tester to carry out the startup value, the similar similar fault recurrence and the highresistance grounding and continuous start...
