This paper presents the results of the development and implementation of an electronic control system of the oxygen sensor heater of an automotive internal combustion engine.Keywords: electronic control system, automobile, internal combustion engine.
Quantitative estimation of different modes occurring in electrical complexes and systems, sometimes causing significant difficulties in the absence of correct initial data and ways to gain the calculation type of task. The article attempts to develop an analytical model in providing the ability to perform engineering calculations as in the training and operation of traction substation equipment and other systems of the DC traction power supply, such as onboard. Theoretical calculations are supported by computational examples to understand the essence of the issue.Keywords: inductance, suspension cable, contact wire, track circuit, partitioning point, rapid circuit breaker, overhead contact line feeder.
The paper suggests expanding the range of options for feeder pillars of alternating current traction power network by introducing one vacuums witch in to the bus of the circuit-breaker based feederpillar. In-troduc in gone vacuums witch open sup new opportunities in organization of relay protection and auto-mation on sections with circuit-breaker based feeder pillars. Operational aspects are considered of relay protection and automation in the new feeder pillar arrangement, with new approaches and specific im-plementation of their algorithms suggested.Keywords: traction power network, alternating current, circuit-breaker based feederpillar, relay protec-tion, automation, algorithms.
