Electrical separation individual circuit prevents flowing shock currents through
contact with exposed conductive parts, which may energized fault the basic insulation

Figure 5.2.2. unearthed circuit separated from the distribution system isolating transformer
is not possible the first insulation fault for the current come through this insulation fault
because lack another point circuit through which the current could come back.
Although there are other protective measures for protection against indirect contact, will
not deal with them for the lack space here and because these measures are not important
and not used often the measures mentioned above.11
