Connected load : It is the sum of the continuous ratings of the load-consuming apparatus connected to the system or any part of the system 6. Demand Factor : It is the ration of the maximum demand of a system to the total connected demand of the system 1 7 7. Utilisation Factor : It is the ration of the maximum demand of a system to the total rated capacity of the system 2 8 8. 3 4 5 9 9. 6 7 T = Time in days (24h), weeks (168h) months (730h) or years (8760h) 8 10 10. 9 10 11 11 Relation between the diversity FD factor and the demand factor DF 12 13 12 11. 14 15 16 13 12. 17 14 13. 18.a 18.b Relation with the coincidence factor 19 20 15 Special cases 21 22 16 Special cases 23 24 17 14. 25 25 18 Examples : 19 Example 1 20 Example 2 21 Example 2 22 The peak is at 5 pm 23 3 24 4 1 2 25 26 Relation between the load (Fld) and loss factors (FLS) 27 Relation between the load (Fld) and loss factors (FLS) 26 Load growth 28 Load growth 27 29 More examples 30 More examples 31 More examples 32 33 34 35 36
