Analysis and classification of cause and effect factors affecting the operating modes of overhead power lines

The relevance of increasing the power supply systems reliability by introducing information-measuring systems for monitoring the overhead power lines parameters is substantiated. The systematization of causal factors influencing the overhead lines functioning in normal mode was made, and the classification of overhead lines operating modes was made. With the use of quality control methods, an analysis and classification of cause-and-effect factors influencing the reliable operation of power lines was carried out. The obtained results are necessary for the implementation of the support and decision-making subsystem of the intelligent information-measuring system for monitoring the overhead lines parameters.
