PH series travelling wave fault location tester is a
new device to meet the needs of testingand
verification for travelling wave fault location equipment.
PH series travelling wave fault location tester is
with three-phase widebandwidth, high-speed current output
channels so that it could playback the complete travelling
wave fault signal with high quality. Thetester 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 tester 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.
