Vacuum circuit breakers(VCBs) for capacitive switching applications experience contact erosion and degraded insulation performance due to pre-strike inrush arcing during capacitor bank closing operations, which elevates restrike probability during subsequent interruption. To address this is-sue, A novel conditioning methodology is proposed, combining equivalent capacitive switching simulations with graded dynamic recovery voltage application. The approach enables both surface modification through controlled arc energy (20%–90% coefficient range) and quantitative dielectric recovery evaluation via multi-level transient recovery voltage (TRV) testing. Experimental results demonstrate that the proposed conditioning methodology not only significantly enhances the capacitive interruption capability of circuit breakers but also effectively reduces the physical footprint of conditioning equipment, achieving system miniaturization that improves engineering applicability. Post-conditioning microstructural analysis confirms non-destructive surface optimization with uniform melt patterns. This study establishes a standardized protocol for field-applicable conditioning and performance assessment, effectively bridging the gap between laboratory tests and actual grid requirements.
