| Method of demand calculation |
| |
| Assume a load pattern of the following type |
| |
| 20 KVA |
30 KVA |
30 KVA |
20 KVA |
| 15 Mins. |

| 10:00 |
10:15 |
10:30 |
10:45 |
11:00 |
|
| |
| Integration period is 30 minutes then |
| Demand (RD) - 10:00 to 10:30 = (20*15+30*15)/30=25kVA |
| Demand (RD) - 10:30 to 11:00 = (30*15+20*15)/30=25kVA |
| Demand - at the end of 11:00 = 25kVA |
