1 Scope
This part of GB/T 2820 defines various classifications for the application, rating and performance of generating sets consisting of a Reciprocating Internal Combustion (RIC) engine, Alternating Current (a.c.) generator and any associated controlgear, switchgear and auxiliary equipment.
It applies to a.c. generating sets driven by RIC engines for land and marine use, excluding generating sets used on aircraft or to propel land vehicles and Iocomotives.
For some specific applications (e.g. essential hospital supplies, high-rise buildings) supplementary requirements may be necessary. The provisions of this part should be regarded as the basis for establishing any supplementary requirements.
For other reciprocating-type prime movers (e.g. sewage-gas engines, steam engines), the provisions of this part should be used as a basis for establishing these requirements.
Generating sets meeting the requirements of this part are used to generate electrical power for continuous, peak-load and standby applications. The classifications laid down in this part are intended to help understanding between manufacturer and customer.
