Influence of pulsed power transmission on radio wave environment is investigated. The power pulses are transmitted intermittently in pulsed power network that is already proposed for an alternative of upcoming smart grids. In contrast to conventional power transmission with continuous electric current of low frequency sine wave, pulsed power transmission may affect surrounding field with high frequency radio noises. In this paper, based on the analysis of electric field strength around a power line, the radio noises generated by various forms of pulsed power transmission are evaluated. As a result, two points are derived. First, though the total of generated radio noise power obviously exceeds that of conventional power transmissions, peak strength of electric field rather falls behind the conventional one. Second, concerning the influence on the radio wave of the lowest frequency 40 kHz that is actually used for standard time and frequency signal, the noise intensity possibly exceeds the weak radio signal tolerance according to the shape of each power pulse transmitted.
