OK! now we are starting to get close.
however, the reference from IEC set of standards into IEEE is strange.
i do know the IEEE 80.
however, i am straggling to figure out the IEC methodology to handle the tough voltage, and there are gaps in the system, as far as can understand.
i really hope to...
Thanks for the information.
however, the figure 1 in page 80 in your mentioned file is providing the ALLOWED TOLERABLE touch voltage.
I was asking about the calculation of the actual developed tough voltage which needs to be lower than the value from figure 1.
moreover, this figure 1 is included...
Hello,
The European standard EN 50522 is describing with full details how to evaluate the touch voltage.
Item 5.4.2 is depicting a design process which is summarized in a flow chart in Figure 5 in the standard.
In my case:
The criteria of earth potential rise (Ue) < double the allowed touch...
