2.2 Isolation of the Device Components
The circuit of galvanic isolated components and the strength of galvanic isolation are shown in
Fig. 2.1 Isolation of the Device Components
Table 2.2 Insulation types
Type
Description
Basic insulation (BI)
The insulation used for active parts of equipment to provide protection
against electric shock. The electrical strength of the basic insulation is
checked by type tests: by applying a test AC voltage, the value of which
is different for different circuits of the Device
Supplementary
insulation (SI)
Independent insulation used in addition to the basic insulation in order to
guarantee protection against electric shock in the event of a failure of the
main insulation. The electrical strength of the supplementary insulation is
checked by type tests: by applying an alternating test AC voltage of
various levels (RMS value)
Reinforced insulation
(RI)
Separate insulation system used for active parts that provides a degree
of protection against electric shock equivalent to double insulation.
