- Scope
- This part presents statistical procedures for the analysis of breakdown time data obtained from groups of electrical insulation systems or from independent samples representing models of insulation systems, under constant electrical stress (or breakdown voltage under long-term stepwise electrical stress) , including numerical examples. This section assumes that electrical factors are the dominant aging factors. As we all know, there are many important aging factors, the specific content should refer to GB/T 23756.1-2009. In addition to being a diagnostic parameter for other long-term influencing factors, this standard does not apply the data obtained from the short-term electrical breakdown test. When using short-term breakdown data as diagnostic parameters for non-electrical influencing factors, reference should be made to other appropriate national standards introduced in Part 2. The purpose of this part is to guide the development of system test procedures, and to put forward some suggestions for the issues that need to be considered when formulating detailed rules for the evaluation of electrical endurance life of electrical equipment insulation systems.
