35、e continuity of load supply through controlled transfer, with or without interruption of power, from two or more independent a.c. sources. This series of standards includes information for the overall integration of the STS and its accessories into the a.c. power network and includes requirements fo
36、r the switching elements, their control and protective elements, where applicable. Part 1 of the series concerns general and safety requirements. Part 2 of the series concerns electromagnetic compatibility (EMC) requirements. This Part 3 of the series concerns methods for specifying performance and
37、test requirements including applicable safety tests referenced in standard IEC 62310-1 for general and safety requirements. This standard applies for single-phase, phase-phase and three-phase static transfers in a. c. systems up to 1 000 V. It takes precedence over all aspects of generic performance
38、 standards, and no additional performance testing is necessary. The requirements have been selected so as to be consistent with compatibility levels for low-frequency conducted disturbances and signalling in public low-voltage power supply systems (see IEC 61000-2-2) as well as to ensure an adequate
39、 level of performance when the STS is applied in diverse critical load situations. The requirements take into account the differing test conditions necessary to encompass the range of physical sizes and power ratings of STS. This standard applies to STS as a stand-alone product, whether presented as
40、 a unit or an assembly of units. This standard does not apply to: devices for d.c. source switching; single source systems; transfer systems using only electromechanical switching devices with interruption of the supply to the load during transfer and intended to be used in emergency power systems o
41、r covered by IEC 60947-6-1; automatic switching devices integrated into UPS covered by the IEC 62040 series of UPS product standards. NOTE Additional or different requirements may apply to STS intended for use on board of vehicles including ships and aircrafts, in emergency power systems subject to
42、a particular regulation e.g. health care facilities, fire fighting or emergency rescue, in tropical countries or where elevations are greater than 1 000 m. 2 Normative references The following referenced documents are indispensable for the application of this document.
