高压是safety标准,不是EMC标准.hi-pot基本标准为L,N对FG打1500Vac;Primary对Secondary打3000Vac,具体打多少要根据工作电压来定,但这是最低要求,也可以打等同的直流电压.
怎麽定?我記得我曾維護過的85~264VAC輸入的電源只用一種條件測試HiPot

找标准看看吧
一二次侧应该要3000Vac.

还有一种可能二次侧与FG相连,1800Vac只是primary到FG的要求,安规上的要求还是会超过3000Vac的(FG与二次侧短开测试),打1800Vac只是为了生产方便而已,不代表只要求1800Vac.

I think following are safety rule:
1500Vac/1 minute for basic insulation.1500 X 1.2 =1800Vac/1 second for basic insulation.3000Vac/1 minute for double insulation,3000 X 1.2 = 3600Vac/1 second for double insulation.
