A calculable impulse voltage calibrator [PDF]

, 2002
The principle, design, construction and uncertainity analysis of a calculable impulse voltage calibrator was described. The uncertainity achieved using the calculable impulse voltage calibrator was significantly lower than using any other method. In high-voltage impulse measurement, the gap between the uncertainties required for testing and available ...

Lightning Impulse Voltage Evaluation

2017
This research studied and developed software for lightning impulse voltage parameters evaluation. Full lightning impulse voltage of 9 cases in TDG program had been used as references for software tested. This software created 2 types of voltage waveform which are mean curve and approximate real curve. Kalman Filter had been used for mean curve.
