Answer / shoaib9786
Star Connection:
1. It is a setup where in one end of each phase is
connected together so as to form a neutral.
2. It is used for variable loadings
3. The line current = Phase current
4. The Line voltage = sqrt(3)* Phase volatge.
DELTA CONNECTION:
1. It is a setup wherein one end of one phase is joined to
starting end of another end so a ring is completed.
2. It is used for balanced loads.
3. There is no neutral in here
4. Line current = sqrt(3)*phase current
5. Line voltage = phase voltage.
Hope that answers

What are the different pre-commissioning tests that are performed on the distribution transformer, power cable and switchgear (11kv)?
if there are six generators (3 gas CATT, one Jenbacher o1 MW each, and two nos Diesel 01 no 01 mw other 0.65mw EDGs ( say), 3 CAtt gas set have identical pole pitch,01mw EDG and Jenbacher gas Set have different pole pitch, how their power connection can be done to connect a common bus bar during installation. in short, how different pole pitched generators power connection can be done to connect a common busbar system through generators incomer ACBs.
How is efficiency of DG set calculated? At many places I found the efficiency to be mentioned in percentage. But at some other places I found kWH/ litres. I want to know how dimensionless percentage value is arrived at?
