WebAC Motor Braking. There are several different methods useful for causing an AC induction motor to brake, or slow down: DC injection uses the technique of energizing the stator windings with low-current DC instead of high-current AC as is the case when the motor runs. Dynamic braking works the motor as a generator, dissipating energy through a ... WebAnswer (1 of 2): 1.because we cannot identify stress strain behaviour in sudden loading. the purpose of tensile test is not only to find the failure point but also to observe the stress behaviour throughout the strain. thats the reason we always conduct test with mild steel as there is lot of str...

Webresponse to an applied test surge. A high- impedance EUT, such as a winding, a clearance or a semiconductor in the block- ing mode, will be stressed by a voltage surge. In these cases, the energy associated with the surge is not significant.
