Answer / ksn murthy ,j.e,electrical
IR Values, Change of Siclikazal, any oil leakages, checking
of HT Lt side Insulator washers, Both Ht Side and lt side
cable terminations. Tx. Body Earth and as well Neutral earth
this is comes to transformer testing this is as per my
knowledge if any mistakes please excuse me.

For 7.5kw star delta starter how to calculate 1. Mccb rating 2. Contactor rating 3. Over load relay rating
how can we know the size of cable cross-section from current rating ?
what can be the causes of capacitor start motor having a higher current that its actual
how we can check new PT ? without name plate.

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.
