High voltage impulse test system with a correction algorithm

摘要

A correction algorithm is used in order to reduce the systematic measurement error arising from the evaluation device of an impulse voltage test system. It is advantageous to install the high-voltage divider as intermediate circuit. This arrangement requires only one high-voltage connection between the components of the test system and the device under test. The correction function uK(t) is the difference between the voltage at the device under test uP(t) and the voltage at the high-voltage divider uT(t).
