25、f IEC 60034 establishes the principal characteristics of a.c. generators under the control of their voltage regulators when used for reciprocating internal combustion (RIC) engine driven generating set applications and supplements the requirements given in IEC 60034-1. It covers the use of such gene
26、rators for land and marine use, but excludes generating sets used on aircraft or used to propel land vehicles and locomotives. NOTE 1 For some specific applications (e.g. essential hospital supplies, high-rise buildings, etc.) supplementary requirements may be necessary. The provisions of this stand
27、ard should be regarded as a basis for such requirements. NOTE 2 Attention is drawn to the need to take note of additional regulations or requirements imposed by various regulatory bodies. Such regulations or requirements may form the subject of agreement between the customer and the manufacturer whe
28、n conditions of use of the end product invoke such requirements. NOTE 3 Examples of regulatory authorities: classification societies, for generating sets used on ships and offshore installations; government agencies; inspection agencies, local utilities, etc. Annex A discusses the behaviour of gener
29、ators covered by this standard when subjected to sudden load changes. 2 Normative references The following referenced documents are indispensable for the application of this document.
