Electric apparatus has in the past several years seen wide use in automatic, remote control, and protection systems on USSR electrified railroads. These articles encompass problems of finding and researching protective methods against short circuit currents, elements and mechanisms of automation, as well as special apparatus for their control One group of articles illuminates problems in the telemechanization of electric traction arrangements; the definition of boundaries of energy dispatching circles, remote measuring of trains, insurance of stability of transmission of telemechanized information along the non-shielded cable and high voltage electric transmission lines. The specific topics include electronic systems of automation and protection of signaling, centralizing, and blocking arrangements; investigatory work into differential protection from damage on the protection line; research into electronic differential protection during external short circuits; output thyristor elements for electronic devices of automation arrangements and relaying of the traction substations; devices of automation arrangement and relaying of the traction substations; devices for verification of automatic, remote control, and protection arrangements; stabilization of temperature conditions of electronic mechanisms of automated and remote control systems; definition of optimal dimensions of energy dispatching section on electrified railroads; device for searching of short circuit points of AC traction network and high voltage transmission lines of the automatic blocking system; choice of minimal frequency of the transformer fed by rectified current; line amplifiers for remote control and automatic blocking communication channels; remote measurement of and current in energy supply system; dynamic characteristics of numbered frequency meters; requlation on busbars of traction substations according to average losses in the tractive circuit; electric locomotive remote control system located in middle of stock; system of suppression of impulse interferences in collecting circuit during transmission of information along the catenary network; electronic arrangement for deformation of effectiveness of action of the train brakes;
