Non-stationary Electromagnetic Processes in power-Intensive Electrical Facilities with Highly Varying Loads

we have shown that the operation of electric arc steel-melting furnaces cause non-stationary and ferroresonant electromagnetic processes in supplying electrical facilities, which are frequently the reason of the decrease in their technical-and-economic efficiency. We have presented the findings of theoretical and experimental researches of non-stationary electromagnetic processes in the power supply system of arc steel-smelting furnaces, including power transformers and thyristor-based compensators of reactive power.
