Rating for DG set and any of electrical machines is calculated in KVA. KVA is calculated as KW/pf. One can calculate the required KVA for DG set with this formulation: (KW/pf)/load rate. For example KW=110, pf=0.8 and one loads the DG at 75%, so KVA= (110/0.8)/0.75=185 KVA.
Diesel Generator
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.

ELECTRICAL DG is most commonly known as Diesel Generators, But the actual name was given for Distributed Generator.
if power consumption is 130 KW. how can it convert into unit per hour.

First of all let us understand what is AMF?Generally all the major industries/companies/institution have the DG for power back up , but when main power is cut off , someone has to go to start the DG and this takes time and also a man has to be kept for this purpose. So to eliminate this process PLC panel is installed to Auto start the DG when main power fails.Working is as follows:-when main power goes , a signal is received to PLC and after a delay DG starts . When the Main supply fail signal is received by PLC then after a delay time, output for ACB/Contactor of DG is ON and DG starts automatically. Also the ACB/Contractor of main transformer if sent OFF Command. When main power comes then the signal is again sent to PLC and PLC off the ACB/Contactor of DG and after 2 seconds it on the ACB/Contactor of main transformer and after 30 seconds it off the DG. DG is sent OFF command a little late so that the load beard by DG for a long time can be compensated by running at no load for some time.
