In power transformer Generally TanDelta Test is carried out To Measure the Insulation Resistance of the Bushing of Transformer ,But You would have Doubt there IR is measures also by a MEGGER but Megger actually (Generally ) as 5KV DC in but in this megger The Insulation is Only Measured But In actually in Tan delta test The Insulation. property of Insulator which have a Capacitance Effect When In Loading Therefore this is Taken out to measures the Loss angle of Dielecrtic . Which is Delta (loss angle of Diectric material) .

A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.
