WebJul 29, 2015 · The images show the AC waveform at the lower and higher settings of the readings when the CT is used to measure current consumed by my table fan. If you observe the higher setting readings, the waveform is a perfect sine wave. If you observe the lower setting readings, the wavefrom is not a perfect sine wave. Why is this?

WebNov 29, 2024 · The spreadsheet ‘CT Saturation Calculator’ is intended to provide quick indication not only of whether or not a CT will saturate in a particular application, but also an accurate indication of the actual waves-hape of the secondary current so that the degree of saturation as a function of time is apparent. Furthermore, the data is available ...
WebMay 22, 2024 · The easiest way to solve for transient waves on transmission lines is through use of physical reasoning as opposed to mathematical rigor. Since the waves travel at a speed c, once generated they cannot reach any position z until a time z / c later. Waves traveling in the positive z direction are described by the function V + (t − z / c) and ...
