Sequence of electrical testing
WebPhase sequence testers are designed to check the direction of phase rotation in motorised machinery with three-phase supplies. Our range of phase sequence indicators provide LED indication of both clockwise and anti-clockwise rotation. Three phase supplies are very common in both commercial and industrial electrical installations within the UK. Web14 Jun 2024 · Phase Sequence Explained. Phase sequence of three phase system determines the direction of rotation of 3 phase induction motor. Phase sequence also decides, if we can connect one 3 phase system parallel with another or not. And hence, it is very important to understand what is phase sequence So, to get the details about phase …
