A shopping complex is planned to be built in Kuala Kangsar, Perak and their loads are listed in Table 2. There is a 1000 kVA distribution transformer at the substation that is located nearby the shopping complex. Currently, the maximum demand for the distribution transformer is 500 kVA and the capacity of the transformer loading cannot be beyond 90% of its rating. Overall, the diversity factor for the whole load is estimated to be 1.5. The building contractor submits their proposal to tap the electricity supply from the existing distribution transformer. As an engineer at the utility company, analyze the coincident maximum demand of the whole complex in order to decide whether their proposal can be approved and give some justifications to support your decision.
