Elimination and suppression of ferromagnetic resonance, has taken various measures

In order to eliminate and suppress the ferromagnetic resonance, to take a variety of measures, the selection of the excitation characteristics of a good TV; openings in TV delta winding open end of the installation of a linear damping resistors or bulbs; open delta windings connected in parallel in TV multifunction computer harmonic  mcb circuit breaker  ; the TV  Circuit breaker  to a neutral point of zero sequence TV; side of the TV once in series between the neutral point and ground resonance eliminator. Operating experience shows, TV wiring measures to curb ferromagnetic  electric transformer  a good effect, so it is widely used in domestic power companies. Together with the 10 kV bus through the TV Burning Accident Zero Sequence analysis of the causes of damage explores the TV and from the TV source parameter design proposed ultra-low frequency oscillation suppression over current solutions.
