standards In order to get the accurate results, we use the ETAP load flow tools Load flow studies shall be carried out for all the critical system conditions that can occur The load flow studies shall include all branch power flows (i.e.: MW’s, MVAr’s and MVA) and the resulting voltage levels at all switchboard busbars and at selected critical MV and LV motor drives.  1.1References   GEDI Ref No
