PROBLEM TO BE SOLVED: To achieve a digital simulated transmission line device responding to increased multichannel applications and is capable of outputting waveform data without phase shift simultaneously, the digital simulated transmission device performing an overall operation test (the test for simulating an actual system failure) for a relay device used in protection of a power system or a fault point locating device employed for monitoring a power system. SOLUTION: There are provided a plurality of first-in-first-out memories 4, in which the voltage and current digital waveform data for each channel are stored. Every sampling timing, the digital waveform data is output from each first-in-first-out memory 4 at the same time, so that the digital waveform data having no phase shift each other are obtained. |
