This part of IEC 62271 applies to all overhead, pad-mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers for rated maximum voltages above 1 000 V. In order to simplify this document where possible, the term recloser (or reclosers) has been substituted for automatic circuit recloser(s) or cutout mounted recloser(s) or both.

The general parameters for this guide apply to 50 Hz or 60 Hz synchronous generators driven by reciprocating engines, steam turbines, combustion turbines, and hydro turbines. The guide generally applies to the stator and rotor of generators with rated outputs of 1 MVA and above. The guide does not address machine auxiliaries or the excitation system.

ASME VVUQ 60.1 provides guidance to computational physics simulation software end users for evaluating and selecting simulation software appropriate for their intended application of interest. The selection should be guided by the level of risk associated with the application of interest. The software can be based on theoretical formulations or empirical data. Before selecting a particular simulation software (either commercial, open-source, or developed in-house), the end user must know its theoretical basis, dependability, and limitations relevant to the end userâ??s application of interest. This Guideline outlines some matters that the end user can take into consideration during the software selection process. A series of questions are also included to help the end user assess the suitability of the simulation software by weighing responses based on the risk associated with their application of interest. The scope of this Guideline is limited to computational physics simulation software. It does not offer guidance on other software. ASME VVUQ 60.1 has been developed to provide guidance to end users to evaluate simulation software based on its functionality. Other aspects such as cost are not considered. This Guideline is not limited to any physics or any specific engineering application.
