Hello,
Don't foreget that during the start of an induction motor the CosPhi is quite different from nominal speed running.
You can not multiply the rated (active) power by the starting current / nominal current ratio to get the active power consumed during the start.
You will find figures in IEC60364 -5-52 describing different methods of installation for wiring system.
You may also find some answer in Electropedia: The world’s online electrotechnical Vocabulary http://std.iec.ch/iev/iev.nsf/welcome

I think Schneider Electric has used this technology for transformer differential protection in the Sepam range.

diffrent between earthing and grounding?
Earthing is used in european electrical installation standards (IEC)
Grounding is used in US electrical installation standards (NEC, UL)
But both are describing the same idea.
For vocabulary question, Electropedia also known as the “IEV Online” (International Electrotechnic vocabulary) is very useful.
