A
I have couple of questions, to which I would love to have some clarifications.
i) How do continuous high voltages on a transformer secondary damage them? (Voltages in range of 1.05 pu to 1.15 pu)
ii) The transformer are generally rated to 1.05 pu at full load, .80 pf and 1.10 at no load. What is the acceptable voltages for the transformers say at 10% loading and unknown pf?
iii) Is low or high power factor preferable during high voltages but low loading?
