Whether capacitor loads can be connected for testing a
diesel engine at its full load capacity? Is there any
limitation of capacotir load? Which is the best load for
testing DG sets?

Answer 1 is correct.
Normally a resistive load is used for testing a DG. As most
DG's are rated at 0.8 lagging power factor the resistive
load is calculated at unity power factor load on the DG.
This is usually 80% of the kva rating. This tests the
engine to full load.
Where it is required to test the generator at full load
also an induction load is used together with the resistive
load to give the correct power factor.
Capacitor loads are not normally used as DG's do not
operate safely on leading power factors.

This is reqd for a 1MW Solar power plant..We have 2DC outputs from the solar panels Connected to 2INVERTOR panels.. Output from invertor is 3ph,280v,500kva,50hz.These are connected to individual ACB.This has to be stepped up to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT BY USING a single two winding 3 ph transformer 11kv/1250kva. or (2)use the two outputs and connect to one three winding transformer of above rating..Pls suggestwith details.
at meter room 50 hrc switch installed,but there are not get earthing proper,so what happen?and 11kv transformer out put going in to hrc main 400a three nog each? so earthing is require for all switch? (some customer made earthing at there home.)
