Answer Posted / shalini
In a star delta connection, OLR will be placed in the
dealta side.
Starting current would be high during the star connection &
timer will be set to switch over from star to delta.
Once the delta connection is activated, the current would
be naturally less & therby OLR doesnot trip.

As per standard, transformer body earthing and other Equipment earthing (Equipment earthing) did not connect. but in LT side termination we are doing metal glanding in both side Transformer to PCC Panel through armoured cable, now X'mer body earthing and PCC Pane earthing (Equipment earthing) both are connect.is this safe for X'mer or other equipment?

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
