How to calculate the diesel generator efficiency? what
details are required to identify the running diesel
generator sets with 1000 kVA & 180 kVA?

Answer Posted / pillay

You did not say what efficiency, whether you get good KWH/ diesel consumption or whether the genset is loaded efficiently
Whatever, you need a KWH METER AND DIESEL CONSUMPTION METER.If you run your 1000KVA gen set for 20 hrs.your genset say at 0.8 pf it could have generated;
1000kva x 0.8 =800KWH per hr .SO FOR 20 Hrs s 16000KWH. If YOUR KWH generated reading says 12000kwh than your generator usage effiociency is 12000/16000 =75%
If the diesel consumption was 600ltrs than kwh/l is
12000/600 =20KWH/Litre diesel. you have to calculate seperately for both of them.
