Hello, Its me again, with another two cents (Hey! maybe this one is worth a nickel... :-).
Clause 2.2.7.4 talks about working voltages for determining Creepage Distances with no apparent distinction between Primary and/or Secondary circuits. The clause lists three bullets, with the third bullet indicating that "short-term conditions (e.g. in cadenced ringing signals in TNV Circuits) shall be disregarded". This clause seems to indicate that for Creepage Distance determinations the ringing voltage is not to be considered as part of the Working Voltage. Of course, it could mean something else (these standards can be pretty tricky...), does anyone have a clearification? Kaan L.
