It is found that the damage of the lines is mainly aroused by heat effect and electric force generated by impulse current circuit, and the effect is different between different current value and different lines. The steady state and transient state shielding efficiency of plate shielding cabin with metal silk net window and without window are measured, and the influence of window to shielding efficiency is analyzed. The result shows that the steady state shielding efficiency rises with frequency.
