WebIn power system studies, the surge waveform is usually defined in terms of wavefront time (T f) and wavetail time (T t). As seen in the figure above, wavetail time is the time when the current waveform reaches half of its maximum value (i.e. T t = T 2). Similarly the wavefront time (or rise time) is defined as 1.67(T 0.9 - T 0.1) or 1.25(T 0.9 ... WebMar 21, 2024 · Monitor Wavefront Proxies. Learn how to monitor Wavefront proxies.
