What are the performance levels of diesel generators?

With the continuous improvement of the quality and performance of domestic and international diesel generator sets, generator sets are widely used in hospitals, hotels, hotels, real estate and other industries. The performance levels of diesel power generator sets are divided into G1, G2, G3, and G4.

Class G1: The requirements of this class apply to connected loads that only need to specify the basic parameters of their voltage and frequency. For example: General use (lighting and other simple electrical loads).

Class G2: This class of requirements applies to loads that have the same requirements for their voltage characteristics as the public power system. When the load changes, there may be temporary but allowable deviations in voltage and frequency. For examples: lighting systems, pumps, fans and winches.

Class G3: This level of requirements applies to connected equipment that has strict requirements on the stability and level of frequency, voltage and waveform characteristics. For examples: radio communications and thyristor controlled loads. In particular, it should be recognized that special considerations are required regarding the effect of the load on the generator set voltage waveform.

Class G4: This class is applicable to loads with particularly stringent requirements on frequency, voltage, and waveform characteristics. For example: Data processing equipment or computer system.

As a communication diesel generator set for telecom project or telecommunication system, it must meet the requirements of G3 or G4 level in GB2820-1997, and at the same time, it must meet the requirements of 24 performance indicators specified in the “Implementation Rules for Network Access Quality Certification and Inspection of Communication Diesel Generator Sets” and strict inspection by the Communication Power Equipment Quality Supervision and Inspection Center established by Chinese industry authorities.
