EMC/NEMP technology from military applications to telecommunications

After describing the fundamental concepts of electromagnetic compatibility (EMC) and nuclear electromagnetic pulses (NEMP), the authors report on the engineering, construction, and test data for a NEMP-protected diesel power plant used as a power source for TLC systems. The test results indicate that the average attenuation (47 dB) of the electric field obtained from the CW test for f=100 MHz, the frequency below which 99.9% of the NEMP energy is concentrated, involves an average interfering signal level of 223 V/m, which cannot compromise the proper operation of the most sensitive electronic circuits since they are housed in the innermost zones. The attenuation of electric field in the NEMP susceptibility test varies markedly according to the geometric configuration of the gen set.<
