This VRMS value is the working voltage used together with the

material group and pollution degree when looking up the

creepage required by a system standard.

To determine if the lifetime is adequate, obtain the time varying

portion of the working voltage. To obtain the ac rms voltage,

use Equation 18.

In this example, VAC RMS = 240 V rms.

In this case, the ac rms voltage is simply the line voltage of

240 V rms. This calculation is more relevant when the

waveform is not sinusoidal. The value is compared to the limits

for working voltage in Table 12 for the expected lifetime, is less

than a 60 Hz sine wave, and is well within the limit for a 50-year

service life.

Note that the dc working voltage limit in Table 12 is set by the

creepage of the package as specified in IEC 60664-1. This value

can differ for specific system level standards.
