Difference Between Standby Diesel Generator And Industrial Power Supply

Oct. 21, 2022

What is the difference between the standby diesel generator and the common industrial power supply? Which one best meets your requirements? In fact, this power generation system has many differences. Although the two will also bring reliable power engineering, they are different. Selecting the wrong type of standby diesel generator may cause you heavy losses. Only when the power grid is abnormal, can the equipment get the best power supply.


Standby power supply refers to the standby power supply that deploys the diesel generator as the main power supply, especially in an emergency. The diesel generator used as the primary power supply refers to the primary power supply. Even large cities cannot avoid power failure. This problem will undoubtedly force you to find a suitable diesel generator to ensure the normal power use of enterprises. Therefore, before purchasing, you should further understand the characteristics of diesel generators to make correct choices.


Jiangsu Starlight Electricity Equipments Co.,Ltd. will talk about the definition of standby diesel generator and common diesel generator


standby diesel generator

The diesel generator is commonly used as the main power supply. The diesel generator can operate 24/7, because the load varies from 50% to 100% of the main rating of the diesel generator.


For example, if the main rated power of the diesel generator is 100kVA, if the load is between 50 and 100kVA, it can operate for countless hours.


On the contrary, the common diesel generator is intended to be used as the main power supply. If necessary, they are designed to run for a long time, including 24/7. They can provide variable power as long as the load change does not exceed 50% to 100% of the rated value of industrial common diesel generators. Because running the main power system below 50% of the rated main load will result in light load. This will reduce fuel efficiency and may damage the diesel generator. Unlike the backup diesel generators intended to serve as backup to the main grid, the industrial main power system is intended to serve as the main power source in areas where there is no grid service.

Low load (when the diesel generator operates below 50% of its rated main load) shall be avoided to prevent damage to the diesel generator. Low load leads to low fuel combustion efficiency, resulting in unburned fuel and reduced efficiency of diesel generator.


The common diesel generator is designed to operate under slight overload at its higher standby rating, but within a short time (about one hour). The standby rating represents the maximum power obtained from the machine.


The standby diesel generator is designed to provide emergency power in case of grid failure. Most are designed to operate for approximately 200 to 250 hours in 12 months. They can provide variable or constant diesel generator loads. As with all power generation systems, the use of a standby diesel generator providing sufficient amperage is essential. This is particularly important during start-up, as most standby diesel generators will only operate at about 70% of capacity at start-up. The bottom line is that the standby diesel generator is designed as the standby power supply of the main power supply.


The standby diesel generator, also known as the emergency diesel generator, is installed in a fixed position to provide service during power failure until the mains power is restored. These diesel generators provide 1 hour backup power within 12 hours.


As more and more power outages are caused by extreme weather and technical failures, the standby diesel generator can provide 200-250 hours of service every year, so it is increasingly popular. You can easily find this type of diesel generator in public places such as hospitals that need uninterruptible power supply and industrial and commercial purposes. Although noise is still a common disadvantage of these diesel generators, the current diesel generator sets also have silent type units. You can contact Jiangsu Starlight Electricity Equipments Co.,Ltd. to obtain more silent diesel generators to meet your requirements.
