What is chopped impulse wave? – TeachersCollegesj

WebMay 19, 2005 · There are two tests, lightning impulse and switching impulse tests. The first is to simulate lightning strikes where the full wave shape is where the voltage crest reaches a maximum at 1.2 microseconds and then decays to 50% in 50 microseconds. The switching impulse test is used to simulate man-made type transients. Mike tlwaggie (Electrical) (OP) WebAs seen, in Figure 3, the chopped impulse allows the shape to be acquired in a smaller time scale, with a more time detailed sweep, resulting in a better evaluation of insulation behavior... south park season 25 ctv

WebThe waveform observed should be identical to applied waveform (other than for amplitude) : then the device has passed the test. (3) Chopped wave test at 115% fullwave amplitude : For this kind of test , the impulse generator would have to be fitted with a rod gap or controlled trigatron type gap.
