Abstract Results are reported of a study on the magnitude of currents passing through the body on contact with a phase or pole of a network comprising a rectifier. Not only the connection circuit of the rectifier, but also the location of the rectifier in the supply circuit is of prime importance for electrical safety and the safe use of networks insulated from earth installed underground. Optimum safety conditions are assured when the rectifier is installed in the immediate proximity of the substation or when the rectifier and supply transformer are housed in the same enclosure. It is recommended that the length of the alternating current cable to the rectifier be kept to a minimum.
