Surge test device for short-circuit tests of components of a high-voltage system and method

摘要

The present invention discloses a surge current tester (100) for short circuit testing of components of a high voltage system, comprising a first terminal (106) and a second terminal (108) for a device under test (104), having a capacitor device (C1) connected to is electrically connected to the two terminals (106, 108) and is arranged to provide a high voltage voltage (Uout) at the terminals (106, 108), with a number of additional capacitors (C2, C3, C4, C5, C6 , C7, C8, C9, C10, C11), which are electrically connected in series with the capacitor device (C1), and with a control device (110) which is designed to monitor a voltage waveform of the high-voltage voltage (Uout) and a additional additional capacitor (C2, C3, C4, C5, C6, C7, C8, C9, C10, C11) in addition to connect in series, when the voltage waveform falls below a threshold (430).
