at our plant there are two transformer. no.1 transformer drawing 300amps at its primary winding and no.2 transformer draining 500amps, but oil temperature of transformer no.1 is greater than no.2 what is the possible cause of this please response

 

Responding to Shafiq's 27-Apr-10 (12:48) query...please provide additional detail. For example, the nameplate ratings of each transformer, the actual voltage and ampere measurements, and lastly, are they connected in parallel?
