How do I calculate the load if kw and voltage is given in a 3 phase application?
Dear sir,
you are stating that you know the kw. Then what else you want. If you want to know the current in amps use usual formula to find out one of the unknown parameter: Kw = sq.rt of 3 * voltage * current * power factor divided by 1000.
If you require current in ampere = kw * 1000 / sq.rt.3 *voltage * pf.
Hope, this clarifies your question. If any thing else required pl. Revert.
How to calculate the ups requirement for 50 desktop computers with CRT 15" monitor each and 20 Dot matric printers with 5 mid size laser printer
This is regarding requirement of UPS capacity required for desktop, monitor & printer... Please enquire with the manufacturer / supplier about wattage or VA capacity of each appliance. Add together. If u are using 3 phase UPS distribute the load on 3 phases equally. Add 20% as a safe margin. This will be equal to your required capacity of UPS.
