Hello everyone,
I'm new to this forum as I ran across some search for my calculations.
I'm doing some load list calculation and I need some info for my look-up table, especially the PF and EFF.
Since the voltages are not mentioned, so I go by the HP. For the 480V, the EFF and PF stop at 200HP.
Questions:
(1) can 300HP mtr be in the LV group, and if so, do you have those corresponding PF and EFF for such motors? From vendors, perhaps?
(2) I aslo have equipments (skid) with 6000HP (as they should be in MV group) but the table stops at 4000HP, and I can't find the PF or EFF either. Is there any assumption for those factors as a rule of thumb?
Really appreciate.
