    Jan 01, 2008Ferroresonance can be avoided by employ- ing gas (SF6)-filled cables [30] for distribution systems above 20 kV. The effect of sunspot cycles and those of nuclear explosions can be mitigated through the use of three-limb transformers with a large air gap between the transformer iron core and the tank [31].
