Hi everybody,
Refering to suntop's initial post, let us note the following paragragh
{{{The strange thing with this motor that we measured the starting current of this motor on different runs we got different readings of the starting current (they are ranging between 287Amp. to 450Amp.)}}}...
hi,
skeandhu
The problem of circulating current is reffered to the incorrect reactive power sharing as bigamp mentioned; this means there are incorrect/inaccurate settings of voltage magnetude and/or voltage droop.
You have to note that whatever the method of reactive load sharing, the need...
Hi,
Besides to the issue of design, the effiecency by definition equals (Pout + Ploss)/Pout; while P loss is approximatly constatnt and indpendent of load, the factor of effiency will increas as Pout increases.

Another point that may add to this topic, is the pressence of third harmonic in the load current. For example, with discharge lamps, the value of third harmoic in each phase current is about 20 to 30 % , this will make a value of 60 to 90 % of third harmoic current in the neutral. Noting that...
