A list of chapters covered in this pamphlet covers the following: (1) Increasing the effectiveness of 3 kV. direct current electrified railroads; (2) Algorithm for calculating traction during a given travel time along a direct current section, accounting for changing tension on the electric locomotive current acceptors under tractive and recuperative conditions; (3) Mathematical model for electrical energy loss calculation in a tractive electrical supply system; (4) Electrical energy loss in transformer assemblies; (5) Improved construction rectifier with natural air cooling on Townsend avalanche diodes, and its loading capacity; (6) Characteristics of inverted rectifier assemblies on thyristors; (7) Research on diode heating conditions during natural cooling and short-lived overloads; (8) Research overloading under rectifying conditions; (10) Overloading rectifiers; (9) New protection schemata for transformer overloading under rectifying conditions. (10) Overloading arising during opening of electromagnetic mechanisms with ferromagnetic cores; (11) Mathematical modeling of processes during graduated regulation of tractive substation alternating current tension; (12) Experimental research on tension spectrum of transverse electrical supply lines; (13) Influence of resistor-condenser contour parameters upon tension distortion of tractive substations with semiconductor transformers; (14) Electrical work safety in non-junction road laying on alternating current sections.
