1 Scope

This section GB/T 2820 specifies the basic characteristics for AC (a.c.) reciprocating internal combustion turbine (RIC) machine.

This section applies to land and marine AC (a.c.) generating sets, but not for aerial or land vehicles and drive locomotive power Units with reciprocating internal combustion (RIC) engine.

For some special purposes (such as hospitals, high-rise buildings essential power supply), additional requirements may be necessary. The provisions of this section it can be used as the basis to determine any additional requirements.

The term of the AC drive (a.c.) reciprocating internal combustion generator speed and velocity characteristics (RIC) machine to be a list of instructions.

For other types of reciprocating prime mover (such as steam engines), the provisions of this section can be used as the basis.
