Answer / hi2know

We know that at maximum efficiency in %= √Pi/Pc * 100 = √900/1600 * 100= 3/4 * 100= 75%

Answer / bala

the exact answer is 72%.because the condition for maximum efficiency is variable loss=constant loss.here constant loss=900,variable loss=1600 at full load.so when variable loss=900 the transformer may reach its maximum efficiency.so efficiency=((900+900)/2500)x100=72%

Why we transmit the power at the voltage in the multiple of 11 or 1.1 like 11kv, 22kv, 66kv, 132kv...... some one told me that it is due to fomr factor 1.1 of sine wave. its fine but while transforming we can choose any voltage, so why only multiple of 1.1 there also.......? plz tell me.
