Received a newsletter from UL. Said that they are looking into updating
standards to account for DC di-electric withstand vs AC. I can understand
that the physics of dc arcing and tracking could be different from ac, but
why would the dc di-electric withstand be more onerous than ac?
Perhaps they

Hi Brian:
Hmm. I wonder if UL knows what UL knows. Mr. Flore
Chiang of UL's Taiwan office has given several papers
at the PSES Symposia on the physics of clearance,
creepage, and solid insulation breakdown.
These are classic papers and should be studied by all
product safety professionals.

Hi John:
Mr. Chiang drew his material from a number of sources,
especially IEC sources, with attributions. Take a
look at his bibliography.
Best regards,
