| Abstract: | Ferromagnetic resonance of voltage mutual inductors for 6 kV power supply system of the oil refinery took place several times, resulting in burn- out of voltage mutual inductors of 6 kV substation, explosion of lightning guards, breakdown of electric equipment, fusing of high voltage fuses and misoperation of relaying protection. Reasons of the above problems are analyzed and precautionary measures are given. |
