This report consists of eight studies. (1) "Reinforcement of energy feeding arrangements" describes the experiments in this area carried out on the East-Siberian road. (2) "Protection of the catenary network during direct current section reinforcement" covers problems of the catenary network concerned with increase in loads and reliability requirements for the energy supply arrrangements, as well as the need for estimating recuperative currents during the choice of protective settings. Included are descriptions of new sectioning post arrangements and forms of protection employed on the East-Siberian road. (3) Areas of utilization and operational experience of linear capacitance compensation in alternating current tractive networks": possible variations of switching on the linear capacitance compensation in A.C. current tractive network with 27.5 kV. tension, and influence of these variations on substation tractive busbars. On the basis of research and operational experience it is determined that the most rational utilization areas are in energy feeding arrangements of feeder cable sections and optimization of operating conditions of the tractive networks. (4) "Arrangements of linear capacitance compensation in A.C. tractive networks"; parameters and definition of fundamental elements as employed on tractive substations and sectioning posts of principle linear capacitance compensation circuits. (5) "Linear capacitance compensation protection and automatics" presents reworked and installed unbalanced voltage protection of high sensitivity power capacitors; by-pass apparatus utilizing fast-acting VAB-28 circuit breakers on the short circuit principle, and a system of control, automatics, and linear capacitance compensation protection. (6) "Operation of parallel compensation arrangements" covers protection from commutational overloads and presents methods for driving the reactor. (7) "Some results of adjustment and operation of automatic blocking arrangements and electronic protection of feeders". (8) "Remote control of energy feeding objectives along the line of energy dispatching" shows characteristics of apparatus for remote control of stations, sectioning posts, and parallel junction points, including emergency signal transmission.
