Power line impulse measurement system

摘要

An impulse measurement system for displaying impulses in an alternating current electromagnetic energy waveform, the impulses generally occurring at frequencies substantially greater than that for the waveform. The system comprises high speed sample memory for recording the high frequency impulses, memory for recording the waveform, and display for receiving the high frequency impulses and the waveform from the high speed memory and the waveform memory, respectively, and displaying both the high frequency impulses and the waveform simultaneously, thereby permitting efficacious identification of the cause of the impulses.
