Directives for selection and application of
transfer switching equipment
1 Scope
This Standard specifies the product properties, technical parameters and
structural types that should be paid attention to during the selection and
application of transfer switching equipment (TSE), and the environmental
conditions in use.
This Standard is applicable to the selection and application of the TSE with a
nominal voltage of no more than AC 1,000V① or DC 1,500V.
TSE is used in the transfer between two power supplies, so as to guarantee the
continuous power supply to the loads. During TSE transfer, it is allowed to
conduct momentary interruption② to provide loads with power supply.
TSE can also be used in the transfer between loads.
