About cabinets and generators
And an overview of cabinet
And the system is designed for diesel generating sets to run parallel design, manufacture of special equipment. Apply 2 and above with electronic governor of diesel generating units running in parallel (if the diesel generating sets for the machinery required to install electronic speed governor). Start with a long-range generating units, and automatic machines, automatic distribution of the ratio of active power, automatic machine by splitting down stand-by generator failure and showed that the protection and other features. To achieve this system of power frequency, running parallel between the active power distribution unit automatically, so that it allows in a given range; be achieved through the operation of power generating units running in parallel between the active power transfer, in order to switch Unit shutdown or unloading.
