BS EN 62310-3:2008 Static transfer systems (STS). Method for specifying performance and test requirements
The BS EN 62310 series of three standards 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 integration 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.
BS EN 62310-1 concerns general and safety requirements
BS EN 62310-2 of the series concerns electromagnetic compatibility (EMC) requirements
BS EN 62310-3 concerns methods for specifying performance and test requirements including applicable safety tests referenced in standard IEC 62310-1 for general and safety requirements
BS EN 62310-3 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 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 level of performance when the STS is applied in diverse critical load situations. The requirements take into account the differing test con...
