Damped Oscillatory Wave Testing is a highly specialised diagnostic procedure for evaluating the performance of electrical systems during transient conditions. In a controlled manner, the method creates a simulated real-world disturbance caused by lightning or switching events. Thus, the damped oscillatory waveforms can take any curve shape or appear as a sum of two sinusoidal function... https://www.emciplus.com/damped-oscillatory-wave-generator.html
