WebMay 24, 2024 · The applied voltage is 5V (cyan waveform) while the current—technically known as the "inrush current"— (yellow waveform) surges very high: its measured value is 26.2 Amps with a time duration of 21.6µs. In this instance, the device, itself, is able to withstand the current transient. Webknown as the Inrush Current. Inrush Current is a form of over current that occurs during energisation of a transformer and is a large transient current which is caused by part cycle saturation of the magnetic core of the transformer. For power transformers, the magnitude of inrush current is initially 6 – 10 times the rated load current.
