Performance Level National Standard GB diesel generator set / T2820 1-1997 "Reciprocating internal combustion engine driven alternator group" Part I: Application, ratings and performance in Article 7 of the diesel generator set provides four properties. (1) G1-level performance requirements apply only provides the basic parameters of the voltage and frequency of the connected load. East China mainly as a general-purpose engines, such as lighting and other simple electrical load. (2) G2-level performance requirements applicable to utility power system voltage characteristics and have the same required load. When the load changes its engine factory in East China, however, may have temporarily allow the voltage and frequency deviation. Such as lighting systems, such as pumps and fans. (3) G3-level performance requirements apply to the right frequency, voltage and waveform characteristics, there are strict requirements for connecting devices. Such as radio communications and thyristor controlled rectifier load. (4) G4 level performance requirements apply to the frequency, voltage and waveform characteristics are particularly stringent requirements of the load. A data processing device or meter grate system. Under normal circumstances the standby unit when you need mains power supply, when the electricity brownouts or other reasons wind up uninterrupted power supply in east engine manufacturers, in order to ensure the user's basic production and life of the generator set. Such turbines standing in the telecommunications sector, hospitals, electricity supply of industrial and mining enterprises, airports and power stations and other important units. Such units to stay in standby state, to provide a continuous supply of electricity for non-constant load. Weifang Huadong Engine Co., Ltd., welcome new and old customers to buy.
