“…Over the last years, open coal mines that increased their outputs, mining machinery fleet, and installed capacities have also seen some increase in the mining electrical equipment downtime due to the damaging of 6 kV PSF. [16,22,21] Power supply system failures at open mines reduce the efficiency of mining machinery, processing sections, and the coal mines as a whole due to the reduced output, increased prime costs, and reduced industrial safety. The analysis of failure distribution across the power supply system components allows one to describe the most typical damages and failures occurring at mining companies.…”

Technological innovation in the mining industry involves the extensive use of new high-power, energy-intensive, and high-performance mining machinery that should be reliable in its operation. The key mining company equipment includes mining excavators, drilling rigs, crushing and screening units, and mine drainage facilities. Providing the fault-free power supply and the efficient operation of the electrical infrastructure of a mining company is a priority, and it depends on the quality of the power supply system and its elements. Power supply system failures reduce the operational efficiency of mining machinery, processing sections, and the mining company as a whole, which results in reduced power consumption, uneven loading schedule, failures to meet the output plans, and increased prime costs for the products. The analysis of the electrical infrastructure power supply system at a mining company shall help us assess the quality of operations and their efficiency and develop actions to reduce the idle times of electrical equipment, provide uninterrupted power supply and plan the activities of the mining company in the wholesale electrical power market more accurately.

Subject of research: methods of relative measurement of higher harmonics for detecting a faulty feeder with a single-phase ground fault. Purpose of research: evaluation of sensitivity of the methodology of faulty feeder search using wavelet transform. Object of research: distribution networks of 6(10) kV. Main results of research: the level of higher harmonics does not affect the performance of the technique, regardless of the point of the fault and the harmonic composition of the load, the damaged connection is the highest value of the spectrum energy.
