My name is ogbebor Monday oszuwa,our company is designing a gas plant(flow station). Please show me how to calculate the electrical load list.I have attached the various machines power rating in horse power,the operating voltage is 380v.frequency is 60hz and power factor is 0.85.I will be very grateful to hear from you.


Thanks.

Dear Sir,

I could not understand your question. But still, I would try to express as below:

Collect data of all electrical driven equipments in following format:
1. Sr. No, 2. Name of equipment, 3. Tag no. of the equipment, 4. whether the equipment is stand by? 5. Name such equipments having standby arrangement as A & B. 6. Write down rating of the equipment KW / HP, 7. Write down name plate current of the equipment.

Make sum of all and exclude the equipment having 1 standby. Thus, you will find your connected load. Then, consider diversity factor as .8, Thus you will find probable load at the time of running of all equipments. On this basis, you will be able to distribute load feeders accordingly. Hope, may be clarifying your question.
