瞬態過電壓是指在極短時間內發生的高電壓脈衝，可能持續幾微秒到幾毫秒。這些過電壓不屬於設備正常運作的工作電壓範圍，但必須被考慮進安全設計，因為它們足以擊穿絕緣或設備損壞。

衰减原因：高温高湿下，水汽渗透到表面处理层，溶解残留离子（如助焊剂、金属离子）形成 “电解液”，离子在偏压作用下迁移，让绝缘电阻降低 —— 就像橡胶吸水后变潮湿，导电能力变强；

設備運行環境中的污染狀況會顯著影響絕緣性能。污染等級越高，越容易在絕緣表面形成導電通路，增加漏電或電弧風險，因此需設定更長的爬電距離。
By streamlining all the process—from purchasing and parts sourcing to PCBA prototyping—you may receive your finished boards in as quick as just one 7 days. Allowing you to definitely iterate, enhance, and produce promptly or even.
工作電壓會直接影響你需要設計的「間隙距離」和「爬電距離」大小。電壓越高，潛在的絕緣需求和空氣/表面擊穿風險越高，安全距離需求就越大。
不同的絕緣措施(如基本絕緣、雙重絕緣或強化絕緣)對爬電距離的要求有所不同，越高等級的絕緣保護，所需距離越長。
