37、ards applies to stand-alone operating a.c. static transfer systems (STS) intended to ensure the 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 integ

38、ration of the STS and its accessories into the a.c. power network and includes requirements for 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

39、(EMC) requirements. This Part 3 of the series concerns methods for specifying performance and 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 transfe

40、rs in a. c. systems up to 1 000 V. It takes precedence over all aspects of generic performance 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 i

41、n public low-voltage power supply systems (see IEC 61000-2-2) as well as to ensure an adequate 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 pow

42、er ratings of STS. This standard applies to STS as a stand-alone product, whether presented as 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

43、of the supply to the load during transfer and intended to be used in emergency power systems or 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

44、use on board of vehicles including ships and aircrafts, in emergency power systems subject to 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 do
