| Abstract: | The defective insulation failures of two LB7-220W current transformers are introduced briefly.When the current transformer has defects,the use of conventional test methods to analyze the characteristics of gas chromatography to determine the methods and steps of the defect type,severity and deficiencies are proposed through the concrete examples.The protective measures for the current transformer's latent faults are presented. |
