Abstract

Abstract

The differential capacitive voltage divider and inductive voltage divider were designed for voltage measurement of magnetically-insulated transmission line (MITL) on a 10-stage fast linear transformer driver (LTD) system. The dividers were calibrated in-situ with a 12 kV pulser. The voltage of MITL was measured with the two voltage dividers. The experimental results show that, the differential capacitive voltage divider signal is susceptible to MITL sheath electrons. But when the electrons are highly insulated, the capacitive divider signal could reflect the history of MITL voltage. There is oscillation in the waveform of inductive divider, which is believed to be resulted from the parasitic capacitance and inductance according to circuit simulations. However, the real voltage waveform could be reconstructed with post-processing according to frequency response analysis.
