| Abstract: | By analyzing the formation mechanism of neutral-ground （N-G） voltage of metro communication and signal power system, the ineluctability of N-G voltage and possible influence on communication and signal device load are discussed. It is suggested that the user, designer and engineer of communication and signal systems should scientifically understand the N-G voltage problem without any misunderstanding technically on N-G voltage, in order to avoid unnecessary waste of resources. |
