Fuel consumption for caterpillar 750 KVA

After adaptation in culture now I must adaptation in working area too. In Nigeria electricity is very bad, in one month only 20 days survive the other one must use generator. It’s a big problem for our company to operate and to produce.
So, our company buys a generator as main supply of electricity about 400KVA. We are preparing fuel supplier and consumption for KVA needed. Characteristic as below for caterpillar 750 KVA
| Genset Spec | kva | kw | V | 3p | Cos Θ | kvar | A |
| 750 | 600 | 400 | 3p | 0.8 | 450 | 1082.56 |
Caterpillar one of leader in generator side, the compartment using soundproof so noise little reduce. This type using 2 filter for fuel as main and one as 1 fuel separator. Using characteristic of caterpillar we get consume of fuel in 100% load is 158,9 lt/h. we can get consume in different percentage load as table shown:
| A Act | A avg | % load | l/h | 24 | l/day | consume for 10000 lt in day |
| 1082.56 | 1082.56 | 100 | 158.9 | 24 | 3813.6 | 2.62 |
| 920.18 | 920.18 | 85 | 135.1 | 24 | 3241.6 | 3.08 |
| 811.92 | 811.92 | 75 | 121.6 | 24 | 2918.4 | 3.43 |
| 649.54 | 649.54 | 60 | 95.3 | 24 | 2288.2 | 4.37 |
| 541.28 | 541.28 | 50 | 85.3 | 24 | 2047.2 | 4.88 |
| 368.07 | 368.07 | 40 | 54.0 | 24 | 1296.6 | 7.71 |
| 243.58 | 243.58 | 30 | 35.8 | 24 | 858.1 | 11.65 |
| 129.91 | 129.91 | 20 | 19.1 | 24 | 457.6 | 21.85 |
Why we must calculate 10000 liters, because our tank capacity is 10000 liters so we must calculate 10000 liters how many days will be run out. So we must schedule for every 4 to top up the tank.
Either in actual condition, our load is less than 400 KVA but we must have schedule for continuity in production.
