Abstract :
A new method is introduced to measure and analyze the EMI in high voltage laboratory. The measuring system includes a hardware system and a software analyzer. The accepted interference signal is analyzed in time domain, frequency domain and synchronously in joint time-frequency domain based on the wavelet theory. The results show clearly the component and amplitude of the interference signal in different frequency range and transmitted through different ways such as radiation or conduction.
