I do not understand why "X" caps should provide a (hi-pot) current path for either primary to protective earth, or primary to secondary.
In any case it is acceptable, for this standard, to test at the sqr(2) * TestV, so 2121 Vdc is appropiate. luck, Brian -----Original Message----- From: [email protected] [ mailto:[email protected]] Sent: Tuesday, August 05, 2003 5:04 PM To: [email protected] Subject: Hipot question I am testing some in-house equipment that is covered under EN61010. Is the AC line touch current limit 3.5 mA at line + 10%? When I run a hipot test am I allowed to use 2121 VDC rather than 1500 VAC? Due to the 0.047 uF X caps the AC hipot current is somewhat high.
