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.

I have a question, I visit 01 site and face a problem, there is 2.5 ton Air Con working, when air con compressor is running at that time rectifier voltages are increasing upto 290-295 v and rectifier is giving main high alarm (rectifier is APC single phase, before starting compressor rectifier voltages was 230v. when air con is going off rectifier voltages are decreasing smoothly at its actual voltages 230v. Load on Genset phases is this: Red-13.5 amp AC (Air Con load), Yellow-1.7 amp AC (BTS lights etc.) and Blew-4 amp AC (telecom system load), Genset phase to phase and neutral to phase voltages are also ok. These are 10 sites having same system and same rectifier APC brand at every site 02 genset are working but the problem is same at all these 10 sites. What will be the reason behind???
