At site, we have 30Kw motor (3 phase, 400V,50Hz) and FLC
54A as per the nameplate. At the time of starting it draws
840A instead of 390A (7.2%). As per the data sheet also its
390A starting current. it thru a dol starter from the MCC.
can anyone tell what is the problem in the motor

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
