Ralph,
The answer to your question is in the US arm of your
own company. Drop a line to James Moellmann, who has
recently been to the IEC meetings in China and IEEE meetings
in Florida all concerned with yet more standards on
MOV-protected devices and equipment.
Regards
Mick

I think this 'particular technology' is an important
point. As I
understand it, devices like Transorbs (TM?) are quite
different from
MOVs, being avalanche diodes with a very high thermal
capacity. They
seem to be rarely used (cost?) but have desirable
characteristics (like
not exploding!). Are there relevant standards?
