These switchgears are the controlling boards which are composed of several monitors. This board analyzes and measures parameters and some cases e.g. current, frequency and voltage. All diesel generators need to control switchgear and board in order to be able to exhibit better function and performance. At this event, they are capable to monitor well functional conditions of diesel generator and variations of related components so that take measure if it necessary.

Application of diesel generator: 1- Turn on and off generator; 2- Control of oil pressure level and water temperature; 3- Control of generator output current; 4- Control of voltage and frequency; 5- Control of fuel quantity
