Summary:A brief consideration of the current sensors with the magnetosensitive elements. The use of reed switches as current sensors in relay protection is advised. The principle of building protections on reed switches is stated. The disadvantages of the known designs for mounting the reed switches in closed complete current conductors are analyzed. Four designs for mounting reed switches near three-phase closed complete current conductors with dividing barriers and on cable lines are proposed. In the first one, the bracket with reed switches is attached to two dividing barriers of the current conductor, in the second to its shell and passes through the dividing barriers, in the third, the reed switch is mounted on a rotary drum located in a housing attached to the cable, in the fourth - on an inclined bracket. Further we speak about how the response parameters of magnetosensitive elements are controlled using these designs.
