Analysis of Transient Electric Fields Caused by the Operation of Impulse Voltage Generator

초록

The transient electric fields, which originate from the operations of a high voltage experimental apparatus and Marx generator, were measured and analyzed by means of the Fast Fourier Transform(FFT) method. The plannar-type electric field measuring system has been developed. The signal transmission system consists of optical fiber links to prevent the effect of electromagnetic disturbances. The electric field measuring system showed a very good step response characteristic and its frequency bandwith was the range from 12Hz to 12 MHz with an amplification factor of 5.
