1. Introduction:
To check the effect of load increase due to the new equipment to be installed in the factory
2. Reference Document:
a. as built drawings
b. latest electrical bill
c. on-hands information by the client's representative
3. Current installation:
a. Single chamber sub-station with 1000KVA Transformer
b. Current size of ACB is 1000A TPN with 1600A Busbar
c. Current MD is 600A
4. New Installation:
a. New equipment (MD = 720A)
b. New a/c load (MD = 86A)
5. Maximum Demand Load Analysis:
a. Future MD (A) = Current MD + New MD
= 600A + 720A + 86A
= 1406A
b. Future MD (KW) = 860KW
c. Future MD (KVA) = 1012KVA
6. Conclusion:
a. New load cannot be catered by existing TNB sub-station
b. Application on new load / increasing of the current load need to be submitted to TNB
c. New MSB need to be installed to cater for future load / to upgrade the existing MSB (1000A TPN ACB to 1600A TPN ACB)
